As always I am totally incapable of following a recipe but this one from Epicusious is the one I used to get a general idea. We started with a lot (probably around 35-40) of plum tomatoes from the farmers market which the Bee helped me wash. I then cut the tomatoes into small pieces and placed them in a Pyrex baking pan. While I was working on that the Bee peeled 3 small green zucchini we also got at the farmers market. She is a big fan of peeling with the vegetable peeler. I then chopped the zucchini and one small onion and added them to the tomatoes. The Bee then helped me to drizzle all the vegetables with a little olive oil, some salt, pepper and garlic and a little Italian seasoning we had. I then put the pan in a 400 degree oven for about 45 minutes, until everything had cooked down and was soft and juicy. After pulling the pan from the oven and letting it cool a few minutes, I took the vegetables out of the pan using a slotted spoon and put them in the food processor. I purposefully left the juices in the pan, so they wouldn't leak out while I blended. I then pulsed the veggies until blended and mixed the veggies back in with the juices to thin it to more of a sauce consistency. We ate some of the sauce that night and it was delicious, a unanimous thumbs up from everyone. The best part is that we have three small batches in the freezer for another day.
