What vegetarian dish goes well with potatoes dauphinoise?!
Dauphinoise potatoes are very heavy and creamy. If you're going with the French theme, then a side of Ratatouille and a French lentil salad would balance things out great.
French lentil salad:
Stuffed peppers,quorn burgers,cheese salad,baked onions stuffed with quorn chicken,tomatoes stuffed with chopped boiled egg and chives and maybe just veggie sausages and some mushrooms.
vegetable soup with a tomato base with potatoes carrots onions garlic brown rice and great northern beans
and if not alcohol then a white grape juice would be light.
Vegetables in a rich tomato sauce, maybe purple sprouting broccoli or green beans
Try mash or french fries for a well balanced meal
