Corn, Bean & Cucumber Salad

1 can beans (I used kidney, but black would be good too)
1 can corn (or 3 cobs worth cooked and cut)
1 large cucumber diced small
1 large tomato seeded and diced
2 large avocados
sour cream
2 cloves garlic minced
1/4 c. cilantro (or more)
2 Tbsp olive oil
juice of 1 lime
1/2 tsp cumin
1/2 tsp salt


Toss all in a large bowl. Serve in a taco bowl with avocados and sour cream.
