How about quinoa (a whole grain) or amaranth or buckwheat or barley or another grain you aren't alergic to? Either as whole, cooked grains (with soy milk and raisins and ground flax?) or dry cereal with soy milk.
Also,there's no reason why you have to have "breakfast" foods for breakfast. Lentil soup with a whole grain (again, whatever you aren't alergic to), bean burritos (in a lettuce wrap or a grain that you can handle). Bean soup? Think out of the (cereal) box!
