We have tons of grape and cherry tomatoes from our garden. When using them in salads and recipes, cutting them in half one by one can be tedious, so we use this trick. Take two shallow-rimmed plates, or two identical flat container lids. Place the tomatoes on one of them, cover with the other so the tomatoes are firmly sandwiched, then use a very sharp knife to cut across the tomatoes perfectly in half. If you don't have a super sharp knife, use a serrated knife. Time saver!
