My dad loves seafood. Fish, shrimp, lobster and everything in between, he loves it all. But one dish that he’s particularly fond of is fish. And I have to say that I’m the same, too.

Whether it’s salmon, cod, or walleye, I’m not picky and love it all the same. When I was younger, my family and I would head up to Minnesota every summer and spend a week there. In between fishing, hiking, and swimming, we always managed to catch a few fish that my dad would fry up for dinner. And those were some of the best pieces of fish that I’ve ever had.

But since I’m not able to catch some fresh fish with my dad this weekend, I came up with the next best thing! This Grilled Haddock Sandwich makes the perfect lunch or dinner and is full of flavor. It’s easy to prepare and great summer meal to impress dad with.
