Preheat your oven to 350 degrees F. Saute ground beef until browned and set aside. Cook your macaroni noodles according to the package directions. When fully cooked, drain and set aside.

In a large bowl, combine the tomato sauce with the chili seasoning, ensuring that it is completely mixed throughout the sauce. Combine the ground beef, macaroni noodles and sauce, and mix in the pepper jack cheese and ¾ cups of the sharp cheddar. Pour into a 9x13 baking dish and top with the remaining ¾ cup sharp cheddar cheese.

Bake at 350 degrees for 20 minutes, or until the cheese is completely melted and beginning to turn golden brown. Easy enough, right?
