Waste not, want not!
So you've made some Roasted Marinara Sauce and have some extra bits of skins, seeds, and other goodies that didn't make the cut? It's really simple to make tomato powder. The uses are endless. Mix even amounts of powdered tomato and water to make your own tomato paste. Add the powder to soups and stews for some added tomato flavor. I thought this would also be good added to meatloaf mixtures. I am sure you can come up with even more ideas!
