Pasta With Sausage Eggplant And Basil

1 large eggplant, cut into 1-inch pieces
1 tablespoon salt
7 tablespoons olive oil
1 3/4 pounds spicy Italian sausages, casings removed, meat shaped into 1 1/4-inch meatballs (about 46)
1 pound cherry tomatoes, halved
6 garlic cloves, finely chopped
1 1/2 serrano chilies, seeded, finely chopped (about 1 tablespoon)
1 1/4 cups canned low-salt chicken broth

1 pound cavatapi or penne pasta
1 cup freshly grated Parmesan cheese
1 cup (lightly packed) fresh basil leaves, torn into 1/2-inch pieces
2/3 cup pine nuts, toasted
Additional grated Parmesan cheese

Toss eggplant with 1 tablespoon salt in large colander. Place over bowl and let stand 30 minutes.
