Egg, Cheese and Onion Gratin with Cherry Tomatoes

Cheese dishes are always popular with children and adults alike, and this is one of those soothing, family supper dishes which everybody will welcome after a tiring day. Sage and cheese together are particularly good, and the whole cherry tomatoes add a fresh juiciness. It could be accompanied by any number of things, but you can serve it with a green vegetable, such as steamed broccoli, or with a salad, and waxy-textured new potatoes are also very good.
