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 frozen corn kernels or canned corn, rinsed and drained to the skillet and spread into an even layer. Cook for about 3 minutes, without stirring, until lightly caramelized.

BUILD SAUCE: Stir in 1 (14.5 ounce) can fire-roasted diced tomatoes with garlic, 1 cup black beans, rinsed and drained, 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 1/2 to 1 teaspoon cayenne pepper if using.
ADD CRUNCH AND CHEESE: Stir in half of the 1 (4 ounce) bag tortilla strips, 1 (8 ounce) package shredded cheddar cheese, and half of the 1 (8 ounce) package shredded Mexican-blend cheese, divided until melted and evenly combined.
FINISH: Sprinkle the remaining Mexican-blend cheese, remaining tortilla strips, and 1 tablespoon fresh chopped cilantro over the top.
