Prepare the Rice:If you haven't already, cook 1 cup of rice according to the package instructions. Set aside.
Cook the Veggies:Heat a large skillet over medium heat. Add a splash of olive oil, then add the chopped red onion and garlic. Sauté until the onion is translucent and fragrant, about 3 minutes.Add the diced red and yellow bell peppers, zucchini, and corn to the skillet. Cook, stirring occasionally, until the veggies are tender but still slightly crisp, about 5-7 minutes.Sprinkle in the ground cumin, chili powder, smoked paprika, salt, and pepper. Stir well to coat the veggies evenly with the spices.
Add the Beans:Add the drained and rinsed black beans to the skillet with the veggies. Cook for another 2-3 minutes, stirring occasionally, until the beans are heated through. Remove from heat and set aside.
Assemble the Burritos:Lay a flour tortilla on a flat surface. Spread a layer of rice down the center of the tortilla, leaving space on the edges for folding.Top the rice with a generous scoop of the veggie and bean mixture.Add a handful of shredded lettuce, a spoonful of salsa, a dollop of guacamole, and a sprinkle of shredded cheese if using.
Fold and Roll:Fold the sides of the tortilla over the filling, then roll the tortilla tightly from the bottom to the top. If desired, wrap the burrito in foil or parchment paper to hold it together.
Rest and Serve:Let the burritos rest for about 5 minutes to allow the flavors to meld together.Serve the burritos warm, garnished with fresh cilantro and lime wedges on the side.
Notes
Tips:
For added flavor, try toasting the tortillas briefly in a dry skillet before assembling the burritos.
Customize the burritos by adding your favorite fillings like sautéed mushrooms, roasted sweet potatoes, or pickled jalapeños.
