RATATOUILLE
2 1/2 lb tomatoes (4 large)
8 large garlic cloves, thinly sliced
1 cup chopped fresh flat-leaf parsley
20 fresh basil leaves, torn in half
1 cup plus 2 tablespoons extra-virgin olive oil
2 lb eggplant, cut into 1-inch cubes
2 1/4 teaspoons salt
2 large onions (1 1/2 lb total), quartered lengthwise and thinly sliced crosswise
3 assorted bell peppers (green, red, and/or yellow; 1 1/2 lb total), cut into 1-inch pieces
4 medium zucchini (2 lb), quartered lengthwise and cut crosswise into 3/4-inch-thick pieces
1/2 teaspoon black pepper
Garnish: Parmigiano-Reggiano shavings and fresh basil
Peel and coarsely chop tomatoes and transfer to a 5-quart heavy pot with garlic, parsley, basil, and 1/3 cup oil. Simmer, partially covered, stirring occasionally, until tomatoes break down and sauce is slightly thickened, about 30 minutes. Toss eggplant with 1/2 teaspoon salt in a large colander and let stand in sink 30 minutes.
Cook onions in 3 tablespoons oil with 1/4 teaspoon salt in a 12-inch heavy skillet over moderate heat, stir occasionally, until softened, 10 to 12 minutes. Transfer onions with a slotted spoon to a large bowl, add 3 tablespoons oil to skillet and cook bell peppers with 1/4 teaspoon salt over moderate heat, stir occasionally, until softened, about 10 minutes. Transfer peppers with slotted spoon to bowl with onions. Add 3 tablespoons oil to skillet and cook zucchini with 1/4 teaspoon salt over moderate heat, stir occasionally, until just tender, 6 to 8 minutes. Transfer zucchini with slotted spoon to bowl with other vegetables.
While zucchini are cooking, pat eggplant dry with paper towels. Add remaining oil (about 1/4 cup) to skillet and cook eggplant over moderate heat, stirring occasionally, until softened, 10 to12 minutes. Add vegetables, remaining teaspoon salt, and black pepper to tomato sauce and simmer, covered, stirring
