If you can’t find grilling shrimp (we get it at the seafood counter in our local grocery store), you can buy extra large shrimp.
Although hibachi shrimp is best served fresh, you can store any leftovers in an air-tight container for 2-3 days. Reheat in a skillet over medium-low heat just until warmed through. Do note that shrimp is easily overcooked, even when reheating.
