Fyi I sub'd kale for 4 times the calcium and twice the protein of spinach
3 egg whites
1/2 tbs. almond milk
1 scoop protein powder
1/2 cup spinach
Place banana, protein powder, egg whites, spinach and almond milk into a blender. Puree until smooth. Generously spray a waffle maker with non-stick cooking spray and prepare waffles as usual.
I served with powdered sugar so I won't tell anyone if you do the same;)
