I first sautéed an onion in olive oil, and a finely minced garlic clove as well as a good amount of cumin. Then added some salt and 3-4 tablespoons of tomato paste. Next I added a finely diced sweet potato and half of a golden beet (because I had it left over). Finally a can of black beans - drained - and 2 cans of water. I let it simmer for a little under an hour. Turned out fine for an impromptu kind of dish :)
