Our take on a Southern classic is super delicious, and kind of tastes like biscuit pizza—the biscuit is flaky and buttery with a fun cornmeal texture, and the tomatoes are tender and juicy without sogging out the crust. Mixing the mayonnaise and cheese together makes things feel even more Southern. Your local farmers’ market will have the most delightfully colorful tomatoes with the best flavor, so search there. For a crispier crust, invert a rimmed baking sheet, which will circulate more air underneath it. You can also reheat this in the oven without sacrificing any taste—just wrap it in foil first.
