If you use slightly less than a 1/2-pound of pasta, you will enjoy extra sauce. Feel free to boil 1/2 pound of pasta and add it in gradually until you've achieved the sauce/pasta ratio that you prefer. The pasta continues to absorb the sauce as it stands. Try sautéing a finely diced onion, in olive oil, for 5 minutes at the beginning, prior to adding the garlic. Additional ingredient options include spinach, mushrooms, bell peppers (any color) or cooked sausage or chicken.
