I know that's quite a promise to meet, but it's true. I have found a very easy way to prepare chard that tastes great!
I found this recipe for chard oshitashi on the Martha Stewart website. You don't need a recipe though; it's that easy.
Wash a large bunch of chard, cut of the ends of the stems, and give it a rough chop.
Put the chard in a bowl. Pour soy sauce on it (the recipe calls for 2 tablespoons). Stir. Let marinate in the fridge until you're ready to eat it.
Easy to make, few ingredients, and enjoyed even by those who don't usually enjoy chard. Highly recommended.
