Pinto Bean Casserole with Hatch Chiles

Preheat the oven to 350 degrees F (175 degrees C). Grease a casserole dish.

Melt bacon grease in a large skillet over medium heat. Add chorizo, onion, and bell pepper; cook and stir until browned and crumbly, 7 to 8 minutes. Add garlic and cook until fragrant, about 1 minute. Add pinto beans and salsa verde; mash most of the beans. Season with salt.

Spread 1/2 of the bean mixture in the bottom of the prepared casserole. Layer with 1/2 of the chile peppers and 1/2 of the cheese. Repeat layers once. Cover with foil.

Bake in the preheated oven until thoroughly heated, about 30 minutes. Remove foil and turn on the broiler. Broil until cheese starts to turn golden brown, 2 to 3 minutes.
