Line a baking sheet with a silicone baking mat.
In a large bowl, combine all ingredients except cooking spray and bone broth. Mix with clean hands until well combined.
Roll into 1½-inch meatballs and place on the prepared sheet. Mist lightly with cooking spray.
In a large skillet over medium-high heat, brown the meatballs on all sides (about 5 minutes). Add the bone broth, cover, reduce heat to medium, and simmer until cooked through (8–10 minutes). Optional: Broil for 2 minutes for extra browning.
Plate over mushroom farro risotto or zucchini noodles. Finish with a grating of fresh Parmesan for a "sketti and meatballs" moment.
