Quesadilla with Sauteed Kale & Cheddar- ust add: Kale, olive oil, garlic. (Optional: fresh herbs.) Sneak some greens into your quesadilla by adding kale cooked in garlic and olive oil. The recipe makes these on a grill, but you can also use a stove top. Don’t like kale? Spinach works, too – just don’t cook it as long.
