This is about as easy as it can get, and incredibly healthy too! You can change the cheese, seasoning, add toppings. This is my (almost) daily lunch...sometimes I'll add an egg, or some white beans. Kale will keep your hair, skin and nails glowing!
Heat some of the olive oil over medium heat in a skillet. Add the garlic clove, then top with the kale. Let sit for a minute then stir. Be careful to not let the garlic burn. The kale will wilt in about a minute or so, then add the tomatoes and the spice. Stir and cook another minute or so, until the kale is bright green and the tomatoes are warmed through. Season with salt and pepper and top with the feta.
