Honestly, you cannot go wrong with this delightful dish or dip for your table. Select the beans of your choice and add any vegetables you like. My version has more of a Greek variation.
In a large bowl, combine the beans, fennel, tomatoes, onion, parsley and olives.
In a small bowl, mix the oil, lemon juice, and basil to combine. Season with salt and pepper.
Add the dressing to the bean mixture, and toss to coat.
Fold in the avocado and serve immediately.
