Combine the minced meat and herb cream cheese in a bowl. Peel and finely chop the onion and add it to the bowl. Add the breadcrumbs, mustard, and Maggi. Mix thoroughly.
If the mixture is too moist, add more breadcrumbs as needed.
Season with salt, pepper, and hot paprika powder. Be careful not to over-season as the Maggi and cream cheese already add flavor.
Shape into 6-8 meatballs.
Heat oil in a pan over medium-high heat. Add the meatballs and fry for 10-15 minutes, turning occasionally, until browned on all sides and the internal temperature reaches 71°C (160°F).
