Yeah but no. Some foods are very easy to grow, but most aren't. Probably the easiest of all is scallions. After eating a scallion keep 1 inch of the base intact, then put it in any container with some water in it, wait a week and you'll have a full brand new scallion. Repeat forever for infinite scallions.
