This is a great way to use leftover cooked spaghetti. Or if you are starting with uncooked spaghetti, you will need to cook about 10 oz. spaghetti to get the 4 cups cooked spaghetti needed to prepare this recipe.
Serve with a quick bagged salad tossed with your favorite KRAFT Lite Dressing.
For added color and flavor, garnish baked pie with 2 tsp. chopped fresh parsley just before serving.
