I want to cook different kinds of breakfast but I always use eggs because I feel it is easier to digest in the morning. What other kinds of protein could I use instead of egg? Some people recommend me to not consume any protein at all, but I feel I need protein in the morning, but something that is not heavy on the stomach.  
Buckwheat is also high in protein if you don't want to eat quinoa. It pairs well with fruits, nuts and raisins and can be a good alternative to oatmeal if you are sick of that.
