My favorite breakfast at the moment are pancakes that I make with just 2 ingredients:
I will also add about 1 tsp vanilla extract if I think of it. I will often heat about 1/3 cup frozen mixed berries in the microwave that I mash to put on top. But even if you have nothing but a banana and an egg it makes for a simple delicious breakfast.
Simply mash 1 medium banana, then using a fork beat in 1 egg (I also use the Ninja to do this if I don’t want to do it by hand). Add mixture to a small preheated pan over medium heat. It can be difficult to flip but it’s possible. As the batter hardens I push the edges toward the center making the pancake thicker and smaller. When the top of the pancake is more cake than batter I flip it. I find this works almost every time. I also have the Perfect Pancake Pan (link below) which makes flipping a lot easier since all you need to do is flip the pan, not the pancake.
Either way, this breakfast will run about 200-250 calories and I find it will satisfy me for hours.
