The problem with eating whole food proteins such as fish, poultry, and red meat is that their presence will still be their when it is time to consume your post-workout meal, which defeats the whole purpose of ingesting a quick digesting meal after your workout. Try eating a food with a low GI and that is also not so hard for the body to digest. Foods with soluble fiber, some fruits with moderate fructose levels (hence low-moderate), and low GI/complex carbs (oatmeal, some grains, caseinate powders, Yogurts that have been fermented). And of course, if you are experienced with the different foods, you can mix these foods to get your GI rating down. Mixing fiberous foods with fats and slow/easy digesting proteins is my recommendtion.
