Baked Crepes With Mushrooms And Tartar Sauce

"Lacy baked crepes filled with mushrooms and topped with tartar sauce. Crepes have graduated to dinner! One of the ways I like crepes is the recipe below. At first, the mushrooms and onion are simmered until soft, and then used as a stuffing for crepes. (Want another mushroom recipe? How about mushroom goulash?) Everything is generously smeared with tartar sauce and baked. Just a little bit. Until the crepes blush. Until they’re whatever you think they should be. "
