In a large skillet, cook the ground beef over medium heat until browned. Drain any excess fat.
Add the chili beans and tomato sauce to the skillet. Stir to combine and let simmer for 5 minutes.
In a baking dish, layer half of the Fritos, followed by the beef mixture, and then half of the cheese. Repeat the layers with the remaining Fritos, beef mixture, and cheese.
Bake in the preheated oven for 20-25 minutes, until the cheese is melted and bubbly.
Let cool for a few minutes before serving. Enjoy!
Notes:
This casserole is perfect for a quick and easy dinner. Feel free to add some diced onions or bell peppers for extra flavor.
