Kakai pumpkins

This adorable little Japanese pumpkin has gorgeous orange-and-green stripes, but that's not the most interesting thing about it.

While most winter squash seeds are surrounded by a white chewy shell, Kakai pumpkins have hull-less green seeds. This lack of hulls make them especially easy to eat as a snack — and a healthy snack at that. Pumpkin seeds are rich in protein, iron, zinc, potassium and other nutrients.
