Homemade Filet-O-Fish Burgers

Finely chop the pickles and red onion. Add all the ingredients to a bowl. Mix until smooth and creamy. Chill for at least 20–30 minutes before using.

Lightly butter and toast the brioche buns. Bake the fish fillets according to the package instructions. Place 3 fish fillets on the bottom half of each bun, top with a slice of cheddar cheese, and return to the oven for about 5 minutes, or until the cheese has melted.

Finish with a generous amount of sauce, place the top bun on.
