Summer seafood is served. 

National Oyster Day is a decadent excuse to treat yourself to the freshly shucked crustacean that is equal parts refreshing and delicious. 

For those who want to dress up their oysters with more than mignonette sauce, Chef Dell Leandro, executive chef at Summer Shack in Cambridge, Massachusetts, has a recipe that involves sliced, sushi-grade tuna and a drizzle of ginger-infused soy sauce.

"For seafood lovers, this is truly the perfect oyster half-shell," Leandro told FOX News. "The layers of flavors pop in your mouth and allow you to experience the uniqueness of the ingredients while still lending to a well-balanced and composed taste." 

"The chilled, fresh ingredients make it an incredibly refreshing and satisfying 'slurp'- perfect for a hot summer day," Leandro added.

Try Leandro's recipe to serve at your backyard barbecue or as a seafood dinner appetizer.
