Is it ALL tree nuts? You could try coconut flour- lots of people who can't eat tree nuts can handle coconut (botanically it's actually classified as a fruit, not a tree nut).
Last night I made some italian braised rabbits- braised in white wine and rabbit stock with onions and garlic, olives and parsley added at the end. Delish! I made a green salad with italian dressing to go with it, and some more of the maple pudding cake.
Tonight it's the rest of the rabbit, but I'm thickening the sauce and serving it over some low carb bread I baked. The last of the maple pudding cake for dessert.
