Black beans are becoming a staple at my house. We cook them in a pressure cooker. We cook them the regular way after soaking. And we buy them in BPA-free cans. Depends on the day and time. With fresh corn, cherry tomatoes, peppers, and other goodies at the farmers market, you can pick everything up you need for this salad except for limes and the beans. This salad is similar to some others I have posted in the past except for the black beans and, importantly, the chili lime vinaigrette. A half cup of black beans have 60 mg of calcium and lots of fiber, plus they taste good. I found this recipe online in a Food Network site and modified it a bit. The actual amounts and proportions of the veggies don't matter. It's all good.
