Melt the margarine, mix the walnuts, almonds, 1/2 c vegan sugar and ground spices together. Grease a 9x13 pan. Layer in five sheets of filo, buttering each with margarine. Now alternate layering small handfuls of nuts with two sheets of filo (buttering each. You can get away with buttering every other sheet, but not more.) until everything is used up. Cut into diamond shape pieces (carefully, with a sharp knife), and bake in a 350 degree (F) oven for I believe an hour and 15 minutes, or til golden brown (I do this by eye).
While it is baking, in a heavy saucepan, heat 1 c water, and the remaining 3 c vegan sugar, and the whole spices. Bring to a boil over low to med heat, and then turn down and cook for ~15 min. When the stuff in the oven is done, pour the sauce over the top and let it set for a few minutes. Eat Hot or cold.
