Place the BBQ sauce and maple syrup in a large pot. Juice the orange and add the fresh orange juice to the pot. Whisk everything together until combined.
Add 12-18 frozen meatballs to the pot and gently stir to coat with the BBQ mixture.
Place the pot over medium-low heat, cover, and allow the meatballs to thaw as the sauce heats up. About 10-15 minutes.
Serve warm or at room temperature.
