Time to cook: 1 hrs. 30 mins.
Heat a large nonstick skillet over MEDIUM heat until hot. Add Ground Beef and cook 8-10 minutes, breaking beef into small crumbles and stirring occasionally. Remove the beef and set aside to drain.
Add olive oil and onion to skillet; cook until nicely browned.
Add ground beef back in, along with garlic, chili powder, cayenne, cumin and salt. Stir to combine.
Add in the beer, diced tomatoes and green chilies, and tomato sauce, then bring to a low simmer. Cover with a lid and allow to bubble and simmer so sauce reduces and thickens, and the flavors intensify, about 1 hour.
After an hour, stir through the cornmeal which will help to thicken the sauce. If sauce starts to get too thick, add a little water, and if it’s not yet thick enough, continue to simmer until desired consistency is reached.
Slice or fold open the bags, and spoon the chili on top of the corn chips. Then top each bag with a sprinkle of cheddar cheese. Allow to melt slightly, then serve and enjoy.
