01 - In a bowl, whisk olive oil with chili powder, smoked paprika, cumin, salt, and black pepper. Coat chicken breasts evenly with marinade and allow to rest for 10 minutes.
02 - Heat a grill pan or skillet over medium-high heat. Grill or pan-fry the marinated chicken breasts for 5 to 6 minutes per side, or until fully cooked and juices run clear. Let the chicken rest for several minutes, then slice thinly against the grain.
03 - In a mixing bowl, combine corn kernels, chopped red onion, diced jalapeño, chopped cilantro, mayonnaise, sour cream, garlic powder, lime juice, and crumbled Cotija cheese. Stir until mixture is evenly coated and well incorporated.
04 - Warm flour tortillas one at a time in a dry skillet for 10 to 15 seconds per side, or microwave covered with a damp towel until pliable.
05 - Lay out each tortilla. Spread a layer of shredded iceberg lettuce over the center, top with sliced grilled chicken, and add several generous spoonfuls of the street corn filling.
06 - Roll each tortilla tightly into a wrap, tucking in the sides. Slice each wrap in half if desired. Serve immediately with lime wedges on the side.
