I saw a great idea for a new way to eat a lot of egg whites without getting sick of them... .... Instead of using egg yolk and mayo (as in deviled eggs) use mashed up avocado and season to taste... I haven't tried it yet, but it looked interesting and is pretty good for you....
Peanut butter, flax oil, oats , brown rice, eggs (whole), MILK, almonds, fatty cuts of meat. Thats all clean stuff, otherwise shit like cream, cheese etc (not too sure as I eat clean)
U can buy powdered oats and mix it into all your shakes. I easily mix 50g whey + 100g powdered oats in a shaker and its 500 cals with water.
