I can't spot Swiss chard at the grocery store without picking some up for my mother. To say she adores it is an understatement. Her favorite way, an omelete. My favorite way, a quiche. She won.
I had asked the manager in the produce department to get me the regular Swiss chard instead of the red veined variety they usually have when in season. I prefer it as the latter bleeds a bit over whatever I'm making and I like a clean green look. An idiosyncrasy, I know, but things like that bother me, As to the taste, there is no difference, so why not go with whatever makes you feel better.
Swiss chard is not only one of the most popular vegetables in the Mediterranean it is also one of the most nutritious, second only to spinach. For more information on its health benefits and the best way to cook it go here.
There is no recipe per se for a Swiss Chard omelette. Just make the omelette in whatever fashion you want but first melt some butter, add chopped onions, brown them, add the steamed or boiled Swiss chard, mix and let it cool. In a separate bowl beat the eggs, figuring on 2 per person, add a little milk if you want, salt and pepper, and the cooled Swiss chard and onion mix, Stir in 1 tablespoon of gruyere or parmesan cheese. Don't overdo the cheese as Swiss chard has a mild flavor and the cheese will overpower it.
Add a couple of tablespoons of butter to the pan and when it is melted and browned a bit add the egg mix. Proceed as you would for a regular omelette and fold once or twice over.
Don't be tempted to add more cheese on the top. You want to enjoy the flavor of the Swiss chard and the extra cheese will detract from it.
