Imagine if you could brag about a pizza that's been made entirely from scratch. Many people say they make pizza from scratch but turn to canned sauce to top it. It's an easy enough ingredient to forget about it when talking about "from scratch," but you no longer have to do that. The recipe that follows will let you boast next time you make pizza when everything, from the dough to the sauce, is truly made from scratch.
This sauce couldn't be easier. Toss a bunch of ingredients into the slow cooker, let it simmer away for several hours, and puree it together at the end. Lots of sauce will be left over. Place the leftover sauce in an airtight container and leave it in the fridge for up to a week, or place it in a freezable container until the next time you get a hankering to make a pizza from scratch.
