About This Healthy Recipe
Seitan fajitas use prepared wheat-protein strips with peppers and onions. Whole-wheat tortillas and a small lime-yogurt accompaniment complete the meal. The recipe is vegetarian, contains dairy and is not appropriate for a gluten-free diet.
Prepared seitan varies substantially by brand. The reference label used for calculation is shown below; sodium can be relatively high, so no extra salt is added. Choose the product that fits your needs and recalculate from its label.
Brown the vegetables and seitan separately in a wide pan. This helps the peppers keep some texture and prevents a crowded pan from steaming everything. Assemble the tortillas just before serving so they do not become soggy.

How This Nutrition Estimate Was Prepared
- Match each listed ingredient to its linked food record or stated label reference.
- Multiply the per-100-g values by the listed gram weight and add the unrounded ingredient values.
- Divide the full calculation by four servings, then round for the cards.
- Recalculate if you change the ingredient brand, amount or serving yield.
Ingredient cells are rounded independently. The footer sums displayed cells; per-serving cards use the unrounded calculation, so small rounding differences are expected. Cooking-water losses affect finished weight, not the fixed four-serving calculation.
The fiber subtotal excludes unquantified fiber from the reference seitan. Sodium depends strongly on your seitan and tortilla labels; this is not a low-sodium recipe.

Before You Start
Prepared seitan varies substantially by brand. The reference label used for calculation is shown below; sodium can be relatively high, so no extra salt is added. Choose the product that fits your needs and recalculate from its label.
Allow 25 minutes overall. Component steps can overlap; check doneness and package directions rather than relying only on time.
Check the seitan label
2 minutesSlice prepared seitan into strips and read its cooking instructions. The estimate uses a traditional seitan product with wheat and soy. Use a chef’s knife (paid link) for even cuts before proceeding. Weigh the listed ingredient quantities with a digital kitchen scale (paid link) before starting this step.
Cook the vegetables
7 minutesHeat half the oil in a wide skillet (paid link) over medium-high heat. Cook peppers and onion until tender with a few lightly browned edges. Transfer to a bowl.
Heat the seitan
5 minutesAdd remaining oil and seitan. Cook according to the package until thoroughly hot; the reference brand instructs heating to 165°F. Add garlic, paprika and cumin for the last 30 seconds.
Combine and brighten
2 minutesReturn vegetables to the pan and add half the lime juice. Toss gently and remove from the heat. No additional salt is listed.
Warm tortillas and mix yogurt
2 minutesWarm tortillas until flexible. Stir remaining lime juice into the yogurt.
Make four meals
2 minutesDivide seitan and vegetables among eight tortillas, two per meal, and serve with an equal share of lime yogurt.
How to Know It Is Ready
Seitan is heated according to its package instructions.
Vegetables are tender with a little bite.
Each meal contains two tortillas with equal filling and yogurt.
What This Meal Provides and What to Consider
Meal Balance
- The measured batch supplies about 35.6 g protein per serving.
- Vegetables and the listed grain or legume portions make this a full meal, rather than a protein-only snack.
Things to Consider
- Contains wheat, milk and soy from the reference seitan; not suitable for celiac disease.
- Sodium is label-dependent and this meal is not described as low-sodium. Fiber from the reference seitan is not quantified and is excluded from the fiber subtotal.
Who May Enjoy This Recipe?
Vegetarian meal planning
People looking for a meat-free meal with a clearly defined protein source.
Home cooking
Brown the vegetables and seitan separately in a wide pan. This helps the peppers keep some texture and prevents a crowded pan from steaming everything. Assemble the tortillas just before serving so they do not become soggy.
Measured portions
People who want to understand how ingredient weights relate to a four-serving batch.
How to Adjust the Meal
Smaller appetite
Serve a smaller portion and save the rest. Recalculate nutrition for the portion you actually eat rather than labeling an unchanged serving low-calorie.
Larger appetite
Add vegetables or another suitable accompaniment, and include those ingredients in the meal calculation.
Protein adjustments
If changing prepared traditional seitan, sliced, check its product label and recalculate. A larger amount may also change texture and cooking requirements.
Substitutions, Dietary Notes, and Allergens
Practical Substitutions
- Use firm tofu in place of seitan and recalculate protein and sodium.
- Use plain soy yogurt instead of Greek yogurt for a dairy-free adaptation; keep wheat and soy allergen checks.
Allergen Information
Contains wheat, milk and soy from the reference seitan; not suitable for celiac disease.
Check packaged ingredient labels for the allergens relevant to you. A substitution changes both the recipe and the calculation.
Storage and Meal Preparation
Refrigerate perishable food within 2 hours, or within 1 hour when the surroundings exceed 90°F (32°C). Use shallow containers and a refrigerator at 40°F (4°C) or colder. Use cooked leftovers within 3–4 days; reheat hot leftovers to 165°F (74°C). Keep raw salad components and dressings separate when that improves texture.
Frequently Asked Questions
No. Seitan is made from wheat gluten. These whole-wheat tortillas also contain gluten.
No. This quick method requires already prepared seitan. Dry gluten needs a separate dough and cooking process.
The listed ingredients provide an estimated 35.6 g protein per one quarter of the batch. Brands and portions can change this value.
Use the 2× or 3× control for gram quantities and serving count. Keep the per-serving estimate as a base guide; use larger cookware or batches and check doneness rather than multiplying the cooking time.
