Preheat oven to 375 degrees. Combine both cans of chili in a bowl. Slice the hot dogs into 1/2" to 3/4" rounds, & mix those in too. Spread the mixture into a 9x13 casserole dish - top with 2 cups of cheddar cheese. Bake for 15 minutes. Top with the precooked tots or seasoned biscuit pieces & bake for another 5 minutes. Cool for a couple minutes, & then serve hot.
