Cooking in a cast-iron skillet on a grill opens up delicious and easy possibilities for stylish sides for your proteins. In this recipe, beefy, simply seasoned New York strip steaks are topped generously with wilted onion rings and grape tomatoes. The vegetables cook in a hot skillet with a touch of sugar and balsamic to encourage caramelization — with no sticking on the grate and nothing lost to the fire. If you don’t have a cast-iron skillet, ovenproof stainless-steel also works. Or you can cook the vegetables on your stove over medium-high heat. The recipe is designed especially for the Yummly Smart Thermometer, but if you don’t have one, check the meat's temperature using an instant-read. The recipe is a Yummly original created by David Bonom.
