My boys and I just went to the small Amish market down the street today.  They had the most beautiful squash flowers I've ever seen.  The owner was telling my sons how if you pick the flowers first thing in the morning you can stuff them, cook them and eat them.  My boys looked at him like he had two heads or something!  They could not believe that you could actually eat a flower.

I don't know that I would actually eat them myself, but they looked really good!
