In a bowl, mix the minced meat, spring onion (or onion), parsley, quark, sambal oelek, parmesan, garlic, and salt and pepper using a fork until well combined and firm. If you prefer not to include garlic, omit it.
Shape the mixture into roughly 20 meatballs.
Heat oil in a coated pan over medium-high heat until hot.
Fry the meatballs for 10-15 minutes, turning occasionally, until golden brown all over and cooked through (internal temperature 71°C / 160°F).
