Black bean salsa. This serves 3-4 as a meal, so scale up accordingly.
1 can black beans, rinsed and drained
1 can corn, rinsed and drained
half a red onion, chopped
2 tomatoes, chopped
a bunch of cilantro, chop the leafy bits and toss the stemmy bits
chili powder, the more the merrier, preferably a good one. Penzeys is great, generic grocery store chili powder is really harsh
some extra cumin if you were afraid the chili powder would be too spicy
lots of granulated garlic
salt to taste
lemon juice (lime would be better)
a bit of oil (optional, but it helps carry some of the chili flavors better)
Mix everything together. Taste & adjust seasonings. Fridge until you're ready to put it out, but it tastes fine warm.
