the physalis family rocks!
purple tomatillos, green tomatillo, pineapple tomatillo, cape gooseberry, among others.
theres a few that arent edible, but most all of them are edible and healthy. some of them are also perennials, actually i
think cape gooseberry is one of the perennials in a warm climate. even the annuals are self seeders, so they keep coming back. super easy to grow, adapt to a lot of climates, but they do like it hot.
