FOR ENCHILADAS
1 tbsp. extra-virgin olive oil
1/2 medium onion, chopped
2 cloves garlic, minced
1 lb. ground beef
1 tsp. chili powder
1 tsp. ground cumin
Kosher salt
Freshly ground black pepper
1 (19-oz.) can enchilada sauce
1 (15-oz.) can corn, drained
1 (15-oz.) can black beans, drained and rinsed
8 flour tortillas
2/3 c. shredded Monterey jack
1/3 c. shredded cheddar
FOR TOPPING
Quartered grape tomatoes
Diced avocado
Finely chopped onion
Fresh cilantro leaves
Preheat oven to 350°. In a large skillet over medium heat, heat oil. Add onion and cook until soft, 5 minutes. Stir in garlic and cook until fragrant, 1 minute more. Add ground beef and cook until no longer pink, about 6 minutes. Drain fat.
Return beef mixture to skillet over medium heat. Add chili powder and cumin and season with salt and pepper, then stir in enchilada sauce. Bring to a simmer and cook until sauce thickens slightly, about 3 minutes. Remove from heat and stir in corn and black beans.
Add a large scoop of meat mixture onto each tortilla and roll up. Place rolled up tortillas side by side in a 9"-x-13" baking dish and top with cheeses.
Bake until cheese is melty, 15 to 18 minutes.
Garnish with tomatoes, avocado, onion, and cilantro.
