For a lighter version of this casserole, you can substitute the all-purpose flour with whole wheat flour and use low-fat milk. Also, feel free to toss in any other spring vegetables you love or have on hand—zucchini and bell peppers are also great additions! If you’re a fan of a crispy topping, mix some breadcrumbs with parmesan cheese and sprinkle it over the top before baking.
