A touch of lime and a little cilantro makes this black bean, avocado, cucumber and tomato salad a perfect companion for grilled chicken or steak. Serve this as a side dish or also delicious served as a dip with tortilla chips. My girlfriend made this recently at a party and I couldn’t stop eating it. I knew I had to make it here. The cucumbers give this a wonderful fresh summer flavor. If you like this, you may also like my Southwestern Salad made with corn.
