In a skillet, cook the ground beef over medium heat until browned. Drain any excess fat.
Add the taco seasoning and diced tomatoes with green chilies to the skillet. Stir to combine and let simmer for 5 minutes.
In a baking dish, layer half of the Fritos, then the beef mixture, and then half of the shredded cheese. Repeat the layers with the remaining Fritos, beef mixture, and cheese.
Bake in the preheated oven for 20 minutes, or until the cheese is melted and bubbly.
Serve hot and enjoy!
