For a sauce with meatballs and sausage you need to simmer for a couple hours to bring the flavors together.
At any price point a fresh sauce takes only minutes to prepare. Use any ingredients that your pocket book allows. In fact, you should only start cooking your sauce as soon as you drop the pasta in the water. Have all ingredients prepped and ready.
Tonights supper: Saute onion, garlic and crushed red pepper. Add a splash of red wine and reduce. Add two chopped plum tomatos. In two minutes add diced San Marzano tomatos. Turn heat to high and throw in a couple handfuls of shrimp. Serve over pasta.
The first three ingredients are a staple. The rest are of your choosing. Any fresh veggie, sun dried tomatos, mushrooms, etc.
