Still buying spaghetti sauce??
Stop right now! It’s zippity do dah easy to make your own. Sauté some garlic and basil and other Italian herbs in EVOO, stir in tomato paste and a can of crushed Roma tomatoes. Season to taste with salt and pepper. I added fresh crushed red pepper and about 1/2 tsp of sugar to take the bite out and then finish with a pat of butter. Start to finish, less than 15 minutes!
