4 cups cooked or canned white canellini beans, drained and rinsed
1/2 cup chopped red onion
1 clove garlic, minced
1/2 cup chopped fresh parsley
1/2 cup olive oil
freshly ground black pepper
salt, to taste
2 cans oil- or water-packed tuna, drained
Mix the beans, onion, garlic, and parsley with the olive oil, and season to taste with pepper and salt. Arrange the tuna on top, mixing lightly without mashing it. Let it sit for about an hour to allow flavors to blend.
