Add anchovies, garlic, and red pepper flakes. Keep an eye on the heat; the garlic should cook but not burn. Stir frequently to dissolve anchovies.
After anchovies have dissolved into the oil and garlic mixture (about 5 minutes), add the olives, capers, and marinara sauce.
Let simmer for 10 minutes, while you cook the pasta according to directions.
Drain pasta and add to sauce; stir, and serve with Romano or parmesan cheese.
This recipe is very quick and easy, but for extra convenience, make the sauce a few days before you plan on eating this. Heat it up and add cooked pasta when you are ready to cook this!
