Preheat oven to 400° Fahrenheit and line a large baking sheet with parchment paper.
Add all of the ingredients to a large mixing bowl, and use your hands to combine the ingredients.
Form the mixture into meatballs the size of oversized golf balls and place on lined baking sheet.
Transfer to oven and bake for 20-25 minutes, until fully cooked. If desired, switch the oven to broil for the last 2-3 minutes to brown the top of the meatballs.
While the meatballs are cooking, prepare the sauce (optional). Place all of the sauce ingredients in a pint jar or small pyrex measuring cup. You want a container just wide enough for your immersion blender.
Place the immersion blender at the bottom of the container. Start blending while holding the blender at the bottom. Don’t move the blender from the bottom until the sauce begins to emulsify and thicken. Once it starts to thicken, slowly move the immersion blender to the top until all of the oil is completely mixed in. It should result in a creamy sauce. Cover and refrigerate until use.
Remove meatballs from oven and serve topped with spicy aioli (optional).
