Why This Recipe Works

Restaurants have an advantage when making multipart dishes such as fajitas—a team of cooks. But we wanted a weeknight version that would involve just one cook and one pan: the trusty cast-iron skillet. Chicken, steak, and shrimp are the usual suspects for fajitas because they’re tender and cook quickly. We wanted to branch out with another popular quick-cooking, tender cut: pork tenderloin. Seasoned properly with a generous amount of a complex, boldly flavored spice mixture, we knew it would be a hit. To fit two tenderloins side by side in a 12-inch cast-iron skillet, we cut the tenderloins in half crosswise. Pounding the cylindrical tenderloins into ¾-inch-thick steaks increased their surface area and helped ensure even browning. First searing the pork and then cooking the vegetables while the pork rested was an easy call to make; because the skillet was already hot, the peppers and onion blistered, softened, and browned very quickly. And in a happy twist, we found that the bits of delicious spice rub left behind after removing the meat adhered easily to the vegetables, distributing more flavor throughout the dish.
