Mexican Bean Salad Recipe

I found this recipe on Yummly.com. I know it as Texas Caviar. It's a great salad and works well when eaten with tortilla chips (kind of like a salsa).

Ingredients
15 ozs black beans (rinsed and drained)
15 ozs kidney beans (drained)
15 ozs cannellini beans (drained and rinsed)
1 green bell pepper (chopped)
1 red bell pepper (chopped)
10 ozs corn kernels (frozen)
1 red onion (chopped)
1/2  cup olive oil
1/2  cup red wine vinegar
2 tbsps fresh lime juice
1 tbsp lemon juice
2 tbsps white sugar
1 tbsp salt
1 clove crushed garlic
1/4  cup fresh cilantro (chopped)
1/2 tbsp ground cumin
1/2 tbsp black pepper (ground)
1 dash hot pepper sauce
1/2 tsp chili powder
