Start by combining shredded chicken, black beans, cheese, onions, green and red bell peppers, corn, and spices in a large mixing bowl. Mix everything until the ingredients are evenly distributed.
Lay a flour tortilla flat on a clean surface. Spoon the filling into the center. Fold in the sides, then roll it tightly into a burrito shape. The goal is to have a snug roll so nothing spills out while cooking.
Heat about two inches of vegetable oil in a skillet over medium-high heat. You’ll know the oil is ready when it starts gently bubbling around a wooden spoon.
Carefully place the chimichangas seam-side down into the hot oil. Fry for 3-4 minutes per side or until golden brown and crispy all around. Transfer to a paper towel-lined plate to drain any excess oil.
Your Chicken Chimichangas are ready to serve! Garnish with sour cream, guacamole, or salsa for added layers of flavor.
