While perfectly delicious as is, this festive bean-and-rice salad also lends itself to endless variation. Replace the tomatoes with diced avocado; switch the bell pepper from green to red; stir in chopped scallion, red onion, cilantro—whatever suits your taste or whatever you have around.

Green bell peppers that are allowed to ripen further become red bell peppers. This extra ripeness from additional time on the vine is why red peppers are sweeter than green ones, and also why they're more expensive.
An unpretentious, exuberantly fruity, and robust red wine will suit this salad well. Look to Australia for one of its many delicious shiraz that just ooze blackberry and chocolate flavors. They're frequently incredible values, too.
