Question

Hello, everyone. My name is Josh, and I was recently challenged a question which asks of a plant which all the parts are edible. So, in a strawberry plant, you can eat the fruit. In a potato plant, you can eat the root. But is there a plant which all its' parts are and can be eaten. Please don't guess, this is a question required for homework. Thank you.
