Penne Vesuviana

This recipe is loosely based on Amanda's Farfalle alla Vesuviana.

1 pound penne or mini penne pasta, cooked al dente (reserve 1 cup pasta water)
3 TBL olive oil
2 tsp minced garlic
4 cups crushed tomatoes (if they're fresh) or 1 28-oz can crushed tomatoes
2 tsp capers, drained
1/3 cup Italian green olives, pitted and chopped
1/4 tsp each oregano and basil
1/8 tsp crushed red pepper
1 tbl dried parsley flakes or 2 tbl fresh Italian flat-leaf parsley
grated Parmesan or Romano cheese for topping

Saute garlic in the olive oil until softened. Add tomatoes, capers, olives, and seasonings, except parsley and cheese. Simmer until the pasta is done. Add pasta water a little at a time if needed to moisten the tomato sauce.
Toss the sauce mixture with the pasta and parsley. Top with grated cheese before serving.
