This is a great, quick, fresh tasting salad with a Mexican "flair" that's easy to whip-up for cookouts or picnics or anytime you're grilling. I got it originally from gloryfoods.com, but have modified it slightly(mainly less oil, more cayenne). It's a terrifc way to use the cukes from your garden and your homegrown tomatoes could easily be used in place of the grape tomatoes. Cannellini beans, garbanzo beans or black-eyed peas can be substituted for the butter beans. Frozen vs canned is a matter of preference.
