Eggs--you can take hardboiled, so they don't need to be made in the morning
Mozzarella and tomato salad.
Full fat greek yogurt, if you're doing dairy, with blackberries/coconut/nuts (depends if you're trying to lose weight--if yes, then no to yogurt and fruit for breakfast).
Leftovers--steak! pork shoulder! What are these breakfast foods you speak of?
Homemade sausage--my roomate makes homemade sausage using pork and herbs, no skins, no chemicals. I just fry up a bit in a pan and I'm good to go.
When I'm really low on time or have nothing suitable in the fridge, I have a teaspoon or two of coconut oil. It really does keep me full until lunch. Fat keeps me fuller than carbs. See also Batty's Butter Balls.
