Bring a large saucepan of salted water to a boil and drop in the young greens and chard and simmer until the stalks are soft but not mushy, 3 1/2 to 8 minutes, depending on how sturdy your greens.☞ TESTER TIP: If you’d like to use some of the thick stalks, add them to the boiling water about 2 minutes before the rest of the greens.
