Directions:Cut out the chard stems, dice, and set aside. Coarsely chop the leaves. In a large skillet, melt the butter and olive oil over medium-high heat. Stir in the garlic and onion, and cook for 30 seconds. Add the chard stems and the white wine. Simmer until the stems begin to soften, about 5 minutes. Stir in the chopped chard leaves, and cook until softened. Add lemon juice and Parmesan cheese.
