Ingredients

1 cup white quinoa (uncooked)
1 Tbsp. taco seasoning
15 oz. can black beans
15 oz. can diced tomatoes (I like fire-roasted with green chiles)
1 yellow onion (or any color)
2 bell peppers (any color)
2 Tbsp. taco seasoning
2-3 cloves minced garlic, optional
1/2 cup blender salsa (or pico de gallo, etc.)
8 large burrito-size tortillas (gluten-free if desired)
Toppings of choice: avocado/guacamole, vegan cheese, vegan sour cream, cilantro, hot sauce, etc.

Make-Ahead and Storage Tips

Cook quinoa and sauté the vegetables a day ahead to speed up assembly. Store the fillings in airtight containers in the refrigerator for up to 4 days. If you’re freezing burritos, wrap them individually in foil or plastic wrap and freeze for up to 2 months. Reheat from frozen wrapped in foil at 350°F until warmed through.

Step-by-step directions

Follow these clear steps to build flavorful, well-balanced burritos. The order follows the natural flow of cooking so everything finishes at the right time.

Rinse and cook the quinoa: Place 1 cup white quinoa in a fine-mesh sieve and rinse under cold water until the water runs clear. Transfer the rinsed quinoa to a small saucepan with 2 cups water (or a 2:1 water-to-quinoa ratio). Bring to a boil, then reduce heat to low, cover, and simmer for about 15 minutes until the water is absorbed and the quinoa is tender. Remove from heat and let it sit, covered, for 5 minutes. Fluff with a fork and stir in 1 Tbsp. taco seasoning while it’s hot so the flavor distributes evenly.
Prepare the produce: While the quinoa cooks, peel and halve 1 yellow onion, then slice it into thin strips. Core and seed 2 bell peppers and slice them into similar thin strips so everything cooks evenly. If you’re using 2–3 cloves of garlic, mince them now.
Sauté the onions and peppers: Warm a large skillet over medium-high heat and add a drizzle of oil. Add the sliced onion and bell peppers to the hot skillet. Sprinkle 2 Tbsp. taco seasoning over the vegetables and toss to coat. Cook, stirring occasionally, until the onions are translucent and the peppers are softened and charred in places, about 7–10 minutes. If you’re using garlic, add the minced garlic in the last 1–2 minutes of cooking so it becomes fragrant without burning.
Heat the beans and tomatoes: In a medium saucepan or in the same skillet pushed to one side, drain and rinse the 15 oz. can black beans. Add the black beans and the 15 oz. can diced tomatoes (fire-roasted with green chiles if you like a smoky kick). Stir to combine and simmer gently for 3–5 minutes so the flavors meld. Taste and adjust seasoning if needed.
Combine quinoa with beans: Add the cooked, seasoned quinoa to the black bean and tomato mixture. Stir thoroughly to combine so each bite has quinoa, beans, and tomato. Heat through for another 1–2 minutes, then remove from heat.
Warm the tortillas: Warm 8 large burrito-size tortillas so they’re pliable and won’t tear when you roll them. You can heat them in a dry skillet for 20–30 seconds per side, wrap them in a clean towel and microwave for 20–30 seconds, or heat them one at a time on a gas flame for a few seconds on each side for a little char. Keep them covered so they stay soft while you assemble.
Assemble the burritos: Lay a warm tortilla flat. Spoon a generous portion of the quinoa-black bean-tomato filling across the center of the tortilla, leaving space at the edges. Top with a handful of the sautéed peppers and onions. Add 1/2 cup blender salsa (or spoonfuls of pico de gallo) over the filling for brightness. Finish with your preferred toppings — avocado or guacamole, vegan cheese, vegan sour cream, chopped cilantro, and hot sauce all work beautifully.
Roll the burritos: Fold the bottom edge of the tortilla up over the filling, then fold in the sides and continue rolling tightly to enclose the filling. If you want a crisp exterior, place the burrito seam-side down in a heated skillet and cook for 1–2 minutes per side until golden and sealed.
Serve: Slice each burrito in half if desired and serve immediately with extra salsa, lime wedges, or hot sauce on the side.

Notes and variations

Spice level: Use mild or hot taco seasoning depending on your preference and choose diced tomatoes with or without green chiles.
Protein boost: Add extra beans or mix in roasted corn or cooked lentils for more texture.
Cheesy option: Sprinkle vegan cheese on the filling before rolling, then warm in a skillet to melt the cheese.
Greens: Stir in a handful of chopped spinach or baby kale at the end of the bean-quinoa step and let it wilt for an extra nutrient kick.
Meal prep: Prepare the quinoa and bean mixture and sautéed peppers ahead of time. Reheat and assemble fresh when ready to eat for the best texture.

Serving suggestions

Pair the burritos with a crisp green salad, tortilla chips and extra salsa, or a simple bowl of roasted sweet potatoes. A squeeze of lime over the top brightens all the flavors.
