I hope your new (?) diet helps you feel much better. Some friends are dealing with no gluten and we are avoiding as many carbs as possible, so have found several items that might be of interest to you. Ground flax, ground almonds, and soy flours can make decent cakes and quick breads that are low carb and gluten-free. Corn meal and corn flours are gluten-free. I haven't tried rice flour, which should be gluten-free but will have the carbs that my diabetic husband needs to control. Another option is cocoanut flour. You can make all sorts of quick breads from muffins to pancakes with these. You should be able to make a quick bread at home, cube it, dry it, and use it like stuffing mix, adding herbs, etc., or go sweet and use it like cereal with milk.
I imagine you already know you can use rice, rice noodles, and instant potatoes. This is manageable, with effort. Google gluten-free and black bean brownies. It is amazing what is out there, now.
