HEAT SKILLET: Place a medium skillet over medium-high heat. Add 1 tablespoon extra virgin olive oil and heat until shimmering.
COOK CORN: Add 1 cup corn to the skillet and spread into an even layer. Cook for about 3 minutes, without stirring, until lightly caramelized.
ADD CHICKEN: Add 1 pound cooked diced chicken and stir to combine with the corn.
BUILD SAUCE: Stir in 1 can fire-roasted diced tomatoes with garlic, 1 cup black beans, ¼ cup diced green chiles, and 1 cup enchilada sauce. Cook for 2 to 3 minutes, stirring occasionally, until bubbling.
SEASON: Reduce heat to medium. Taste and add ½ to 1 teaspoon cayenne pepper if using.
ADD CRUNCH AND CHEESE: Stir in half of the tortilla strips, all of the cheddar cheese, and half of the Mexican-blend cheese. Mix until melted and evenly combined.
FINISH: Sprinkle the remaining Mexican-blend cheese, remaining tortilla strips, and chopped cilantro over the top.
SERVE: Remove from heat and serve immediately.
