Toppings: cilantro, sour cream, salsa, guacamole or hot sauce (optional)
Directions
Preheat the oven to 425F (220C). Line a rimmed baking sheet with foil or parchment and lightly coat with 1 tablespoon olive oil.
Combine beef, onion, green chiles, chili powder, cumin, garlic powder, and salt in a medium bowl and mix until well incorporated.
Wrap the tortillas in a damp paper towel and microwave just until softened, about 30 seconds.
Spread about 3 tablespoons beef mixture over half of a tortilla in a very thin layer that reaches the edges. Spread about 1 tablespoon beans on the other half. Sprinkle all over with about 2 tablespoons cheese. Fold in half to make a taco and place on the baking sheet. Repeat with the remaining tortillas, meat, and cheese. Brush the tops with the remaining oil.
Bake, flipping halfway through, until lightly browned, toasted, and crisp around the edges, 30 to 35 minutes. Serve with the desired toppings.
