Preheat your oven to 375°F (190°C).
Heat a 12.5-inch oven-safe skillet over medium-high heat.
Add the avocado oil and ground beef. Cook for 5 to 6 minutes, breaking the beef into small pieces with a wooden spoon, until browned.
Add the diced yellow onion, poblano pepper, red bell pepper, and fresh jalapeño. Cook for 6 to 8 minutes, stirring occasionally, until the vegetables have softened and most of the moisture has evaporated.
Add the minced garlic, chili powder, ground cumin, smoked paprika, and kosher salt. Cook for 1 minute, stirring constantly, until the spices are fragrant.
Stir in the drained black beans and frozen corn. Cook for 2 minutes to heat through.
Pour in the enchilada sauce and stir well to combine. Bring the mixture to a gentle simmer and cook for 3 to 4 minutes, allowing the sauce to thicken slightly.
Stir in 1 cup of the shredded cheddar and Monterey Jack mix.
Gently fold in the corn tortilla wedges until they are evenly coated and distributed throughout the beef mixture.
Sprinkle the remaining grated cheeses evenly over the top of the skillet.
