Recipe adapted from Simply in Season
Chop ½ onion and one bunch chard. Using butter or olive oil, sauté chopped chard stems and onions until beginning to be tender. Add chopped chard leaves and continue sautéing until tender.
Combine chard and onions with 4 beaten eggs, 1 cup milk, 1 cup shredded swiss or cheddar cheese, 1 cup cubed bread, and ¼ cup grated Parmesan cheese. Pour into a greased 2-quart baking dish. Cover and bake in preheated oven at 375° until set, 25-30 minutes.
