Is there any list of absurdly productive food plants? Like if you only have x amount of space or can only by y number of plants, what do you grow to produce the largest raw mass of food possible

So zucchini is the prototypical example, right. And I know of a few others, like tabasco peppers for example

Tell me in the replies, what plants do you know of that make gardeners say "help, I have more x than I know how to deal with, can anyone come take some home?"
