Line a baking sheet with parchment or foil and spray with olive oil cooking spray. Preheat oven to 400.
Combine all ingredients in food processor and mix until a crumbly dough forms. Using a large cookie scoop (1 1/2 Tbsp), form mixture into balls (makes 20-24) and drop onto a lined baking sheet. Flatten out with a spoon or the palm of your hand into disks. Spray tops of each with cooking spray.
Bake for approximately 20 minutes or until beginning to brown on top.
