Oven to 425f, In a food processor finely pulse/chop onion, celery and mushroom. Add all to a large bowl as you work along.

Sauté mixture on med- high heat with a 1/4 c avocado oil for 10 minutes -- this will cook out most of the liquid from the batch.

In that same veggie bowl you have used add the meat, almond flour, salt, eggs and add the veggie mix once it's cooled to the touch. Mix with a sturdy wooden spoon or your hands.

Grab an ice cream scoop and 2 sheet pans with parchment paper. Scoop the meatballs out and leave an inch between each meatball. Cook for 20 minutes.
