Go to almost any Italian restaurant around here and you're almost always served a small bowl of marinated room temperature white beans to enjoy with your bread and oil while perusing the menu. here's my take on it using walnuts and sage to dress the beans.
4 cups cooked cannellini beans (or alternatively 2 15 ounce cans, drained and rinsed)
1/2 cup finely diced red onion
1/3 cup walnut pieces toasted in a 350F oven for about 8 minutes
1/3 cup olive oil
Juice of one lemon
4 Tbl torn sage leaves
1 clove rough chopped garlic
1 Tbl walnut oil
1 tsp salt
1/2 tsp black pepper
1/3 cup water
1/2 cup chopped Italian parsley
Salt and pepper to re season if desired
Cool the walnut pieces after toasting them and the rough chop them and place in a bowl of a mini food processor along with the olive oil, lemon juice, garlic, sage leaves, salt, pepper, walnut oil and water. Process until smooth.
Combine the beans and the diced red onion and add the dressing. Stir in the chopped parsley and refrigerate for a couple of hours to let the flavors blend. Remove from the fridge and bring the salad up to room temperature. Re season with salt and pepper if desired.
