Ingredients

2   (8-ounce) halibut fillets, skin removed
2 tablespoon all-purpose flour
1/2 teaspoon salt
freshly ground black pepper
1 tablespoon olive oil
2 tablespoon mayonnaise
1 tablespoon dijon mustard
1 tablespoon chopped fresh dill
2   kaiser or other large sandwich rolls, halved and toasted
1   tomato, sliced
1   red onion, thinly sliced

Directions

Rinse fish and pat dry; set aside. In a shallow dish, stir together the flour, salt, and pepper to taste. Dip each fillet in the flour mixture to coat.

In a skillet, heat oil over medium-high heat. Cook the fish in the hot oil for 2 to 3 minutes per side or until golden.

In a small bowl, whisk together the mayonnaise, mustard, and dill. Set aside. 

Spread the dill mayonnaise evenly on the rolls. Place a fish fillet on each roll and top with tomato and onion slices
