4 ciabatta rolls, halved horizontally
1/2 teaspoon fresh lemon juice
1 ounce baby arugula

Season steak with salt. Grill, flipping once, until medium-rare, about 8 minutes per side. Let rest 10 minutes.
Brush cut sides of rolls with garlic oil to taste. Grill rolls, cut sides down, until slightly charred around edges.
Whisk remaining teaspoon olive oil,
