Building the plate:
Fire up the grill and throw on the steaks. Cook to your desired temperature, I recommend medium rare. One the steaks are ready, pull them off to rest and toss on the shishito peppers. Blister the outsides of the peppers, and remove from grill.
Cut the steak into one ounce cubes. Using a bamboo skewer or a pick, pierce a shishito, and then a cube of steak. Top with the pesto, and enjoy!
