My favorite type of sauce is the chunky kind with added zucchini, olives, carrots, or mushrooms. I often add even more vegetables to the sauce to enrich both the texture and nutritional value of this meal. I always cover the pot of boiling water with a lid so it will cook faster. I never waste time cooking the sauce and washing a separate pan. Instead, I heat the sauce by adding it over the already steaming noodles.
Spaghetti sauce is also good over rice, especially wild rice.
Another quick meal with spaghetti sauce involves popcorn. I cook up a huge pot of popcorn and dump a whole jar of sauce into an additional bowl. I then dip the popcorn into the sauce. The cleanest way to eat this meal is to put the sauce directly over the popcorn and eat it with a spoon. The drawback of this method is that the sauce deflates the popcorn.
