6 medium sweet bell peppers (a mixture of red and yellow)
5 tablespoons olive oil
1 large onion, quartered and finely sliced
4 cloves garlic, bruised
6 tomatoes, peeled, seeded, and chopped
6 large basil leaves, torn into small pieces

Cut pepper lengthwise, de-rib them, and remove stems and seeds. Slice into strips ?-inch wide. Set aside.

Warm olive oil in skillet over low heat. Add onion and garlic and saut? gently until they are softened, 12-15 minutes. Add pepper strips and saut? gently for 5 minutes, tossing. Add tomatoes, cover, and cook gently, stirring occasionally, until peppers are tender, 20-25 minutes.

Flavor improves if peperonata is made in advance and allowed to cool. It can be made 2-3 days in advance and reheated as well.
