Healthy and low-calorie cookies/galettes

I woke up this morning and had the sudden idea to make some cookies! I just took a pen and wrote down the list of ingredients that I thought would taste good and that I already had at home. It's fun to make something out of things you already have in your kitchen. It was purely experimental; had no idea if it would turn out good or not.

Ingredients
1 large banana
3/4 cup of old-fashioned oats
1 egg
1/4 cup of shredded mozzarella cheese

...and of course, be creative and add whatever you like. I might try that with peanut butter next time. Also, you might want to add some honey or sugar if you have a sweet tooth. I personally didn't add any sweetener. I don't even add sugar to my coffee these days. Acquired taste is a funny thing; never thought I'd enjoy the bitterness of black coffee and appreciate food that are not heavily flavoured. Somewhere during my childhood, my mom said that candies, soda and juices make you thirstier, and I'm not sure whether she indirectly taught me to not like sugar, but I became one of those kids who didn't like candies, ha.

Anyways, back to my awesome cookies...

Directions
1. Mix all ingredients together. I just used my hands.

2. Scoop the batter onto a stray after greasing it with whatever you have. I used butter that I melted in the microwave.

3. Bake at 350F for about 20 minutes.

Tadaaa!

Personally, I hate long lists of ingredients, and ingredients that I don't use often. These cookies (or galettes) are so easy to make and so healthy, except for maybe the cheese, but I love cheese!

I made 6 big cookies, and each cookie was like...80 calories. So awesome!

I don't want to say this but, damn, I'm so smart sometimes!

PS.: I added peanut butter instead of cheese and it was even better!
