In a large mixing bowl, combine the shredded chicken, black beans, corn kernels, diced red bell pepper, taco seasoning, lime juice, salt, and pepper. Stir gently until all ingredients are well mixed and coated in the taco seasoning.
On a clean surface or cutting board, lay out the whole wheat tortillas. Spread a generous spoonful of Greek yogurt (or sour cream) on each tortilla, leaving approximately an inch of space around the edges to prevent overfilling.
Evenly distribute the chicken mixture in the center of each tortilla. Top with slices of avocado, then sprinkle a good amount of shredded cheddar cheese over the entire filling.
To assemble each wrap, begin by folding in the sides of the tortilla. Next, roll the tortilla tightly from the bottom up, ensuring the filling is securely enclosed.
Preheat a large skillet or grill pan over medium heat. Place the wraps seam-side down in the heated pan. Cook for about 2-3 minutes on each side, or until the wraps are golden brown and the cheese is melted.
Once done, remove the wraps from the pan and allow them to rest for one minute. This will help keep the filling intact when slicing.
Slice each wrap in half diagonally and garnish with freshly chopped cilantro, if desired, before serving.
Notes
Serve with extra Greek yogurt or sour cream and lime wedges for dipping.
