You could eat an omelette made with 2 eggs (high protein), spinach, mushrooms, tomatoes, etc, with a slice of whole grain toast, or simply scramble 2 eggs and have spinach and whole grain toast on the side.
Actually, you can eat eggs any way you want them... even frying them isn't bad if you use no calorie cooking spray.
Have a carton of Greek yogurt (high protein) with a serving of fruit.
Make yourself a protein shake, using a high quality shake mix.
