- 1 medium-size firm eggplant
- Salt and pepper
- 2 tablespoons extra virgin olive oil ( EVOO ), plus more for drizzling
- 1 pound sweet Italian sausage with fennel seed, casings removed
- 1 small onion, finely chopped
- 1 rib celery, finely chopped
- 3-4 cloves garlic, finely chopped
- 1 can crushed San Marzano tomatoes (28 ounces)
- A few fresh basil leaves, torn
- 1 pound penne rigate or whole grain penne rigate
- Grated Parmigiano Reggiano cheese
Bring a large pot  of water to a boil.
Peel about half the skin from the eggplant in strips. Chop the eggplant into bite-size pieces; sprinkle with salt and drain for a few minutes on paper towels.
In a large skillet , heat 2 tablespoons EVOO  over medium-high, two turns of the pan . Add the sausage and cook, stirring, until browned and crumbled, about 3 minutes, then add the onion, celery and garlic. Pat the moisture off the eggplant. Stir the eggplant into the sausage mixture; season with salt and pepper. Partially cover and cook to soften the eggplant, 6-8 minutes. Add the tomatoes and basil and simmer the sauce to let the flavors combine, 5-7 minutes.
Meanwhile, salt the boiling water and cook the pasta until al dente. Stir about 1 cup of the starchy cooking water into the sauce, then drain the pasta and toss it with the sauce. Adjust the seasoning. Serve in shallow bowls  topped with cheese and a drizzle of EVOO.
