This was inspired by the sweet 3-bean salads my mother always made me eat, but I didn't take an immediate liking to. I created this recipe when I had a company pot-luck and no money. It was a big hit and no one knew it was made out of the bareness of my cupboards. It's filling and refreshing. It uses fresh summer vegetables. I use dry beans, but you could save time by substituting the equivalent amount in canned beans drained. Also makes a nice meatless main dish on hot summer evenings.
