Double the Spoonfuls

1 Make the homemade caesar dressing by whisking together all ingredients other than the water in a medium bowl. Thin with 1-2 tablespoons of water for a thinner and more pourable dressing (see note).
2 Heat 2 tablespoons olive oil in a medium skillet over medium heat. Add panko breadcrumbs and stir constantly until they are evenly golden, 5-7 minutes. Season lightly with salt then remove from heat so that the bottom layer doesn't burn.
3 Pat steak dry with a paper towel then coat both sides with salt and pepper. 
6 Heat remaining teaspoon of olive oil in a cast iron skillet over medium high heat until glistening. Add steak and cook for 4-6 minutes on each side, depending on the thickness of the steak and how you like it cooked (see note). Let rest on a cutting board for about 10 minutes then slice into thin strips against the grain at an angle.
4 While the steak rests remove lettuce leaves from heads (chop them if you like) then add them to a large bowl. Toss with as much of the caesar dressing as desired.
5 Plate dressed lettuce on a large platter or multiple plates then top with the toasted panko breadcrumbs, lots of grated parmesan, and the sliced steak.
