Step 1

Place the ground beef and onion in a large skillet over medium heat.

Step 2

Cook, stirring occasionally to break up the meat, for 6–7 minutes, or until the meat is cooked through. Stir in the diced green chiles.

Step 3

Preheat oven to 350 F.

Step 4

In a medium bowl, stir together the salsa and sour cream.

Step 5

Pour a few tablespoons of enchilada sauce into the bottom of a 13x9-inch casserole dish. Swirl until the sauce covers the bottom of the pan.

Lay a tortilla on a flat work surface. Spoon 1–2 tablespoons of the sour cream mixture on top, and spread it around the tortillas.

Step 7

Spoon ½ cup of the beef mixture into the center of the tortilla, and roll it tightly. Place in the casserole dish.

Step 8

Repeat with the remaining tortillas.

Step 9

Pour the remaining enchilada sauce over the top of the tortillas. Sprinkle with the cheese.

Step 10

Bake for 10 minutes, or until the cheese is melted.
