Cajun salmon sandwich with goat cheese and lemon mayonnaise on ciabatta

For the sandwich:

3) Slice ciabatta roll lengthwise and place under the grill until lightly golden. Spread goat cheese and lemon mayonnaise on roll. Arrange salmon, lettuce, tomatoes and onions on roll.

1) In a medium bowl, combine cayenne pepper, salt, paprika, black pepper, garlic, onion powder, gumbo file and crab boil seasoning, if using.

For the goat cheese and lemon mayonnaise:
1) In a medium bowl, mix the goat cheese, mayonnaise, lemon juice, parsley, salt and freshly ground black pepper, to taste.
