Banana Oatmeal Cookies with chocolate chips and walnuts

This has to be the simplest and healthiest cookie recipe I've ever whipped up... And they taste great too!!! I found the original recipe on pinterest, which I couldn't help but modify. The basic recipe was simply bananas and oatmeal, which would probably be great too, but we loved these. 

Here it goes:

2 bananas (mashed or pureed)

1 cup of oats

1/2 cup of chocolate chips

1/2 cup of chopped walnuts

1 tsp Vanilla extract

Preheat oven to 350 degrees. Mix all ingredients. Spoon onto cookie sheet. Bake 15 minutes. Remove from a cookie sheet and allow to cool. Enjoy!
