Instead of using jar spaghetti sauce, you can do a simply quick and easy sauce. Brown your meat of choice and drain. Use can tomato sauce and I like to use puree as well as it has a thicker texture. I also like to diced tomatoes, usually the flavored diced tomatoes. I add my minced garlic, onions, fresh basil, flat leaf parsley and oregano. I also add a little sugar to cut the acidity of the tomatoes. Add your drained meat in and let it simmer for about 20-30 minutes (if you have time).
I have also boiled my pasta with fresh chopped herbs as well! Happy cooking!
