Instructions

Step 1:
Preheat your oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with cooking spray to prevent sticking.

Step 2:
In a large skillet over medium-high heat, cook the ground beef, breaking it apart with a spoon, until browned and crumbly, about 8-10 minutes. Drain any excess fat.

Step 3:
Stir the salsa into the cooked ground beef. Reduce the heat to medium and simmer for about 20 minutes, or until the liquid is mostly absorbed. Add the drained chili beans and cook until heated through, stirring occasionally.

Step 4:
Spread the crushed tortilla chips evenly across the bottom of the prepared baking dish, creating a crunchy base layer.

Step 5:
Spoon the beef and bean mixture over the tortilla chips, spreading it out evenly.

Step 6:
Spread the sour cream evenly over the beef layer. Sprinkle the sliced black olives, chopped green onion, and diced tomatoes over the sour cream.

Step 7:
Top the casserole with the shredded Cheddar cheese, spreading it evenly to ensure a cheesy, golden topping.

Step 8:
Bake in the preheated oven for about 30 minutes, or until the casserole is hot and bubbly, and the cheese is melted.

Step 9:
Remove from the oven, let cool slightly, and serve warm. Garnish with extra green onions or a dollop of guacamole if desired.
