Heirloom Zucchini

I didn't know that zucchini is one of the most genetically modified foods until recently, so when I saw organic heirloom zucchini at the Farmers Market, I decided to try it since it was the same price as the rest. It was green and white with thick skin and a coating of soft reddish spines that rubbed off when I washed it. The taste was, of course, very similar to normal zucchini, but stronger. I had it with spinach and sole.
