Preheat the oven on 400°F/205°C.
In a large pot or saucepan, brown the ground beef with the seasoning, diced onions, and salsa. When the ground beef is at least 75% cooked through, add the can of roasted green chiles with the liquid, can of chili beans with the sauce, and the cream cheese. I break up my cream cheese into chunks so it blends easier.
Turn the heat down to medium-low and simmer for 10-15 minutes, stirring occasionally. While the beef mixture is simmering, prepare the toppings you want to use.
When the cream cheese has fully melted, add in 1 cup of Frito corn chips and ½ cup of shredded Mexican cheese. Stir and transfer the mixture to a large casserole dish. Place the casserole dish (uncovered) in the oven and let bake for 10 minutes.
Add remaining Fritos and a layer of shredded cheese. Bake for an additional 5 minutes or until the cheese is melted and browned to your liking.
Add cold toppings and serve. Enjoy!
