Spaghetti Sauce. What kid (and admittedly adult!) doesn't like a big, giant bowl of saucy spaghetti? Despite the fact that Lucas has now entered the "I will not eat vegetables" stage, he loves this sauce. He even helps cut up the tomatoes (using a butter knife), measure the ingredients, and set the timer.
The most important thing here is to only use ingredients and spices that your family likes. If you're not huge on basil, omit it. If you love garlic, add more. Use my recipe as a guide to make your sauce, well, YOUR sauce.
He's my start-from-scratch version of sweet spaghetti sauce, have fun customizing it into one your family will love.
