Can someone please tell me what this plant is? I bought it thinking it was zucchini and planning on making some bread. After opening one up, I am now doubting my initial assessment. The skin is very hard (like it would be on squash), the inside is on a yellow side and is granular. It also does not smell like zucchini....I am completely lost here and have no idea what to make with the already open one...HELP please!
