Hiding chunks (or bits) of crab meat in this fancy mac and cheese gets your kids eating protein-rich seafood hidden within one of their favorite dishes! You might even get away without telling them there is any seafood or crab in their mac and cheese at all. But it can be challenging to get your kids to eat seafood. One of our favorite things about making macaroni and cheese with crab meat is that your kids might eat it too! Seafood and especially crab, is healthy, low in fat, and high in protein.
