We used to dig them up around my dad's Wisconsin cabin when he was still alive. Looks yours had been cleaned before you bought them, otherwise it can be a real challenge to get all the grit out of them (think leeks but on a much smaller scale).
My absolute favorite ramp dish is a cream soup with potatoes.
They're awesome in scrambled eggs, too. My dad's favorite thing was something he called "wild breakfast". He would make scrambled eggs with ramps and morel mushrooms he had picked, and then serve wild asparagus on the side.
