Sometimes you can't beat the classics. ;)
Marcella Hazan's Tomato Sauce Recipe makes an excellent tomato soup, as well. Up the tomato content, thin with chicken broth, and/or add evaporated milk, all to taste. This summer I've been cooking with fresh tomatoes from the garden, so very rough measurements.
Then, make TheKitchn's "The Best Homemade Thin-Crust Pizza" recipe, mixing in a heaping tablespoon of minced garlic to the dough. Flatten small sections of dough (very thin!) with a rolling pin, and fry in a dry cast iron skillet on high heat. Brush with butter as you remove the flatbread from the skillet.
Serve warm, and enjoy!
