Young and tender chard stems require little extra thought, but when the stalks turn thick, and perhaps stringy, it's usually best to trim them from the leaves. That doesn't mean you should toss them in the compost or garbage bin, though. Treat them as another vegetable and you have an ingredient for pickles, gratins, and more.
• Refrigerator pickles: These pickled chard stems are spicy, sweet, acidic, and especially pretty when made with rainbow chard.
• Gratin: A little extra cooking can turn chard stems tender and sweet. For inspiration, see Sunset's Chard-stem Gratin with breadcrumbs and cheese.
• Dip: Swiss chard stalks and tahini are combined in a Middle Eastern dip reminiscent of baba ghanoush. We like this recipe from Taste of Beirut.
• Vegetable stock: Toss the stems in the freezer along with other vegetable scraps. When you've collected enough, make an easy vegetable stock.
• With the leaves: In most cases you can eat chard stems in the same dish as the leaves. If the stalks are thick, finely chop them and start cooking them a little earlier so they become tender.

The stalks in the jar look like very colorful licorice.
Why do you post this literally the day AFTER I threw out my chard stems? I tried to sautee some and they were too fibrous for me to enjoy, but some of these other ideas never occurred to me. Haha, I guess I'll try them out next round!
I would have left my stems whole to make pickles if I'd have seen this yesterday! But my two year old thought it was rhubarb so she walked around the house munching on the raw stems. (Her dad likes to eat raw rhubarb - not even dipped in sugar!)
kls2003, you need to comment on the "how to get your kids to eat veggies" post!
I love love love chard stems on top of a tart with a ricotta/cream base - so healthy! so decadent!
also very good in a basic stir fry like Mark Bittman's classic here:
