Allow enough time for dough to thaw according to package directions.
When thawed, smash each loaf into a ball, then roll into a 16-inch circle to form pizza crusts.
For the steak:
Heat grill to high. Brush steak on both sides with olive oil and season with salt and pepper. Sear steak on hot grill until you see char marks on both sides, about 2-3 minutes per side.
Brush seared steak with 2 tablespoons of balsamic glaze and continue grilling and turning, until cooked to medium-rare doneness, about a total of 5 minutes per side or 140 degrees internal temperature.
Remove steak from the grill to a cutting board, tent loosely with foil and let rest for 10 minutes.
