recipe from: http://www.simplyrecipes.com/recipes/three_bean_salad/

INGREDIENTS
1 15-oz can cannellini beans, rinsed and drained
1 15-oz can kidney beans, rinsed and drained
1 15-oz can garbanzo beans, rinsed and drained
1/2 large red onion, chopped
1 medium bell pepper (any color)
1 cup (lightly packed) fresh flat-leaf parsley
1/3 cup apple cider vinegar
3 to 4 Tbsp granulated sugar, to taste
1/4 cup olive oil
2 cloves garlic, minced (jarred)
1 teaspoons salt
1/4 teaspoon black pepper

DIRECTIONS
Chop bell pepper into very small pieces. Chop onion into small pieces, then add to a food processor and pulse until pieces are very small. In a large bowl, combine all of the beans with the pepper and onion.
In the bowl of a food processer, combine oil, apple cider vinegar, salt, pepper, sugar, garlic and parsley. Pulse until mixed and parsley is finely chopped.
Add the dressing to the bean mixture and mix until coated. Chill beans in the refrigerator for several hours, to allow the beans to soak up the flavor of the dressing.
