And it's the easiest plant to grow in your garden, J_B! It last for ages & seems to almost thrive on neglect! I grow the "rainbow chard" variety - pink, purplish & golden stems - & plant them in my flower beds amongst the flowers & shrubs. Very pretty!
Then, any time I need a "green" boost in a soup, casserole, whatever, I pick some leaves & throw 'em in. The very young, tender ones can be eaten raw in salads. The way I usually prepare chard (silverbeet) is to add shredded leaves to olive oil, garlic & dried chili. A chick saute & Yum! Nice on steamed rice, too, when you crave a bit of simplicity.
