Brown meat and chopped onion in a large skillet. Add 2 tbsp. each of the chili powder and cumin. Stir and simmer for 5 minutes. Transfer the meat to a four quart crockpot and stir in the other ingredients, mixing well. Cook on high for 4 hours or low for 8 hours. Taste and adjust seasonings. Add salt and pepper if needed and a little bit of water if the chili is too thick. Serve topped with plenty of grated cheddar cheese. Enjoy with good friends around a campfire.
