Preheat large Dutch oven over high heat until hot. Add 1 teaspoon olive oil and Ground Beef. Cook 8 to 10 minutes, breaking into small crumbles and stir occasionally. Work in batches if necessary to avoid overcrowding the pan and stewing the beef in it’s own juices. Remove beef; set aside.
Heat remaining 1 teaspoon oil over high heat. Add onion; cook until evenly browned. Add cooked ground beef, chili powder, cumin, garlic and cayenne powder. Season with salt, as desired. Stir until combined.
Stir in beer, tomatoes and tomato sauce; bring to a boil. Reduce heat, cover, cook 1 hour until chili thickens. Stir in cornmeal. If chili becomes too thick, add a little water. If chili is not thick enough, simmer until desired consistency is reached.
Slice or fold open bags; spoon beef chili on top FRITOS® Corn Chips. Top each bag with a sprinkle of cheddar cheese. Allow to melt slightly, then serve and enjoy.
