When you start with a selection of ready-to-go ingredients, burritos become a 20-minute recipe. Your microwave speeds heating time too.
In bowl, combine chicken, cheese, corn and chili powder.
Place 2 tortillas on work surface. Spread each with 1/3 cup beans. Place about sixth of roasted peppers down center of each. Top each with 3/4 cup chicken mixture, flattening slightly. Fold up tortillas, envelope fashion, enclosing filling. Transfer burritos, seam side down, to microwave-safe platter large enough so burritos don't touch. Repeat with remaining tortillas, beans, red pepper and filling. (If platter is not large enough, microwave in 2 batches.)
Microwave burritos on high for 5 minutes (internal temperature 150°F). Serve with garnishes, if desired.
