Simplest Asparagus Gratin
Cover cooked asparagus with cheese, stick it under the broiler until the top is golden brown and crisp around the edges, and you have a fabulous and elegant dish. You can prepare any of the variations using asparagus instead of the suggested alternative vegetable. Other cooked vegetables you can use: green or wax beans, artichoke hearts, fennel, eggplant, leeks, spinach, celery root, parsnips, zucchini, winter squash, or sweet potatoes.
