Grilled Fish Sandwiches Recipe

Preheat a grill pan (or a nonstick skillet) over medium-high heat until it's very hot. Brush the cut sides of the 4 hamburger buns with the 2 tablespoons of melted butter.

Drizzle a little oil into the hot pan, then use a wad of paper towel to carefully wipe out any excess. Place the buttered buns cut-side down and toast them until they're deep gold, about 1-2 minutes. Set them aside.

Add the oiled fish to the hot pan. Cook, turning once, until the fish is cooked through. The cooking time will vary depending on the thickness of your fish, but expect it to be somewhere between 2-4 minutes per side.

Serve the fish immediately on the toasted buns, slathered with the garlic aioli and your chosen toppings, like pickles.
