To make the spicy marinara sauce: Combine the onion, carrot, celery, garlic, tomato puree, and broth in a large, deep saucepan and cook over medium heat until reduced by 1/3. Add the salt, and red pepper flakes, to taste.

For the eggplants: Heat 4 tablespoons of canola oil in a large skillet, over medium-high heat, and fry the eggplant. Drain them on paper towels and sprinkle with sea salt.

Stir the cooked eggplant into the marinara sauce. Keep the sauce warm.

For the pasta:

Bring a large pot of salted water to a boil and cook the pasta to al dente, about 6 to 8 minutes. Drain the pasta, and add it to the marinara sauce. Stir in the grated cheeses.

Divide the pasta among the plates and top with a strip of ricotta salata and some fresh basil.
