For an extra layer of flavor, try adding caramelized onions to the sandwich. Feel free to substitute the flat iron steak with another cut, such as sirloin or ribeye, adjusting the cooking time as needed. If you don't have an outdoor grill, you can use a grill pan or skillet on the stovetop. Experiment with different types of mushrooms, such as cremini or shiitake, for a unique twist.

Follow The Directions
01
StepPreheat an outdoor grill to medium-high heat and lightly oil the grate. (5 minutes)
02
StepCut the steak into 6 thick strips. Season generously with salt and pepper. (2 minutes)
03
StepGrill the mushrooms for 5-6 minutes over medium-high heat until they begin to soften and release their juices. Remove the stems and separate the mushrooms. (6 minutes)
04
StepIn a bowl, toss the grilled mushrooms with salt, pepper, sherry vinegar, and extra virgin olive oil. Set aside. (3 minutes)
05
StepGrill the steak strips for 3-4 minutes per side over medium-high heat, until medium-rare or to your desired doneness. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C). Let the steak rest for 5 minutes before assembling the sandwiches. (12 minutes)
06
StepIn a small bowl, whisk together the barbecue sauce, cider vinegar, and vegetable oil to create a tangy and flavorful sauce. Set aside. (2 minutes)
07
StepTo assemble the sandwiches, spread mayonnaise on the hot dog buns. Layer with arugula, cherry tomatoes, the grilled steak strips, and the marinated grilled mushrooms. Drizzle generously with the barbecue sauce mixture. Serve immediately and enjoy! (5 minutes)
