I had a poster (is that what you call someone who comments?) ask for the recipe for this so here it is. Its really easy!
Toss 1 lb cooked pasta with a drained 12 oz can of tuna in oil, a 26-oz jar marinara sauce and 1/2 cup chopped green or black olives. Sprinkle with chopped parsley.
Thats it! Yummy and quick!
