Cook the rice: Start your brown rice according to package directions. Fluff and let it cool slightly so it doesn’t steam the tortillas later.
Prep the chicken: Pat chicken dry.
In a small bowl, mix 2 teaspoons chili powder, 1 teaspoon cumin, 1 teaspoon smoked paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon oregano, 1 teaspoon salt, and 1/2 teaspoon black pepper. Toss chicken with 1 tablespoon olive oil and the spice mix.
Cook the chicken: Heat a large skillet over medium-high with 1 tablespoon olive oil. Cook chicken 5–7 minutes per side until cooked through and lightly charred at the edges.
Rest 5 minutes, then dice or shred.
Sauté the veggies: In the same skillet, add sliced bell peppers and red onion with a pinch of salt. Cook 5–7 minutes until soft and slightly caramelized. Stir in corn for the last 2 minutes.
Season the beans: In a small pot, warm black beans with a big pinch of cumin, chili powder, salt, and a splash of salsa.
Simmer 3–4 minutes and remove from heat.
Build a simple rice mix: In a bowl, combine cooked rice, juice of 1 lime, a handful of chopped cilantro, and a pinch of salt. This keeps the rice bright and flavorful.
Set up your assembly line: Warm tortillas briefly to make them pliable. Lay them out and line up rice, beans, chicken, peppers/onion, cheese, and a spoonful of salsa or Greek yogurt.
Assemble: For each burrito, add about 1/3 cup rice, 1/3 cup beans, 1/2 cup chicken, some veggies, and a sprinkle of cheese.
Avoid overfilling; it makes rolling harder and reheating uneven.
Roll tightly: Fold the sides in, pull the bottom over the filling, and roll snugly to seal. If meal prepping, keep wet add-ins like avocado or lettuce for serving day-of.
Optional crisping: For a toasty exterior, place rolled burritos seam-side down in a dry skillet over medium heat for 1–2 minutes per side.
Cool before storing: Let burritos cool on a rack 10–15 minutes to prevent soggy tortillas from trapped steam.
