Nut roast
A nut roast or roasted nut loaf is a rich and savoury vegetarian dish consisting of nuts, grains, vegetable oils, broth or butter, and seasonings formed into a firm loaf shape or long casserole dish before roasting and often eaten as an alternative to a traditional British style roast dinner. It is popular with vegetarians at Christmas, as well as part of a traditional Sunday roast. Nut roasts are also made by Canadian and American vegetarians and vegans as the main dish for Thanksgiving or other harvest festival meals.
