Ingredients

• 2 tablespoons vegetable oil
• 2 teaspoons garlic powder
• 1 tomato, sliced
• 1 avocado, sliced
• ½ cup fresh spinach leaves
• 4 sandwich rolls, partially split
• 4 teaspoons softened butter
• 4 (4 ounce) thinly-cut flat iron steaks
• 8 thick slices fresh mozzarella cheese
• 2 teaspoons balsamic vinegar, for drizzling

Recipe Instructions

Step 1

Preheat an oven broiler on high heat.

Step 2

Open the sandwich rolls and spread each with about 1 teaspoon of softened butter. Sprinkle each buttered sandwich roll with about 1/2 teaspoon garlic powder.

Step 3

Broil the sandwich rolls about 5 minutes, until the edges are slightly charred. Set aside.

Step 4

Heat a large, heavy skillet over high heat, and add the vegetable oil. When oil just begins to smoke, drop in the flat iron steaks and quickly sear until steaks are browned, about 3 minutes. Flip the steaks and sear the other side for another 3 minutes; remove steaks immediately, or lower the burner temperature and cook to the desired degree of doneness. Set steaks aside and keep warm.

Step 5

Assemble each sandwich roll with spinach leaves, tomato and avocado slices on one side, and 2 slices of mozzarella cheese on the other side. Sprinkle the tomato and avocado side with about 1/2 teaspoon of balsamic vinegar, and place a hot browned steak on the mozzarella cheese. Fold each sandwich closed to serve.
