This orzo with kale sauce is a delicious vegetarian pasta dish. Kale is usually used in stews, but did you know you can do so much more with it? I’m a huge fan of kale myself. This versatile vegetable is one of the healthiest out there! Kale is packed with vitamins. According to this source About 250 grams of kale contains a whopping 2600% of the RDA for vitamin K, 700% of the RDA for vitamin A, 180% of the RDA for vitamin C, 52% of the RDA for manganese, 20% of the RDA for copper, and 20% of the RDA for calcium. That’s a huge amount!
