Here?s a steak-and-potato dinner disguised as a salad and perfect for a warm- weather supper. This hearty meal features juicy seared New York steak and roasted potatoes infused with woodsy rosemary. Crisp radish, fresh cucumbers, golden tomatoes, velvety avocado and peppery arugula get tumbled in a creamy dressing that?s spiked with just enough horseradish to keep things interesting. The dressing does double duty as a savory steak sauce. Brioche croutons add a buttery crunch?if you can stop yourself from eating them right out of the oven!
