Preheat oven to 350 degrees. Slice tomatoes and place half of the slices in a single layer on the bottom of a baking dish. Add 2 to 3 anchovies on top of each tomato slice. Top each tomato slice with another tomato slice, making a sandwich out of the anchovies. Season with crushed red pepper and olive oil. Bake 20 minutes.
Drain pasta and mix with tomato and anchovy mixture in a large pasta bowl. Toss with spoons to break up the tomatoes. Add salt and pepper to taste. Garnish with chopped parsley and fresh Parmesan, to taste.
