Preheat oven to 350 degrees.
In a cast-iron skillet, cook chicken breasts until fully cooked. Shred chicken and return to skillet. Cook with 1 tablespoon olive oil, red onion, garlic, and red pepper until vegetables are crisp-tender, about 2 minutes.
Add black beans, corn, and salsa or enchilada sauce to the skillet. Turn off the stove and remove skillet.
In a medium bowl, whisk together 2 tablespoons olive oil, cornmeal, white whole-wheat flour, coconut sugar, baking powder, salt, and 1 egg. The mixture should resemble a crumb-like streusel.
Sprinkle this mixture over the top of your skillet. Top with sharp cheddar cheese.
Bake in preheated oven for 25-30 minutes, or just until the cheese is bubbly and barely golden.
Garnish with cilantro or scallions. Enjoy!
