2- Next, process the vegetables 3 medium carrots, 2 heaping handfuls of spinach, 1 small onion, and 2-3 garlic cloves in a food processor until they’re finely chopped.

3- In a large bowl, combine 1 lb ground beef with 1 lb ground pork, turkey, or bison, then add the processed vegetables, ½ teaspoon sea salt, and ¼ teaspoon coarse ground pepper.

4- Mix everything by hand until it’s evenly combined, but don’t overdo it to keep the meatballs tender.

5- Shape the mixture into golf-ball-sized meatballs and place them evenly in the prepared dish.

6- Bake the meatballs in the preheated oven for 35-45 minutes until they’re cooked through and juicy.

7- Once done, let them cool a bit before serving with sides like mashed potatoes or sauces for a complete meal.

8- For meal prep, these meatballs are freezer-friendly, so you can make a big batch and store them for later.
