Brazilian Black Beans

This is improvised from my nanny's Brazilian husband. She told me what was in it, and I kind of went from there.

1/2 pound (or more) bacon, diced
1 onion diced
3 cloves garlic minced
4 cans (or 6, depending on how many leftovers you want) black beans
water, as needed

Fry bacon till done in a large stockpot. Drain off all but about a tablespoon of fat. Saute onion and garlic in bacon fat. When translucent and tender, add beans. Reduce heat to low, simmer 1-2 hours or more. Add water as needed. Consistency should be thicker than stew.

Serve in bowls with shredded cheddar or jack cheese on top
