Pre-heat oven to 350 degrees and line baking sheet with foil. Spray with cooking spray and set aside.
In a large bowl, mix together all ingredients: ground turkey through salt. Using a small cookie scoop or a tablespoon, form meatballs and place in a single layer on baking sheet.
Bake until golden browned, about 30 minutes, flipping once halfway through the cooking time.
Serve meatballs on a platter with toothpicks and extra guacamole for dipping.
