Bring a large pot of water to a boil and add salt. Add the pasta and cook until al dente, about 12 minutes. Drain, reserving about 1/2 cup of the pasta cooking water.

Pour the pasta into a warm serving bowl and toss well with the ratatouille, parsley, and basil. Season with salt and pepper. Thin with the pasta cooking water as needed. Sprinkle half of the Parmesan on top and toss again.

Serve immediately, dusted with a little of the cheese. Pass the remaining cheese at the table.
