Take mince meat out of the fridge and let come close to room temperature.
Dice the onion and mince the garlic.
Mix onion, garlic, milk and breadcrumbs in a bowl and let sit for at least 5 minutes.
In the mean time, roughly chop the sun dried tomatoes, black olives and feta cheese.
Once the mixture has come together in to a sludge add the mince, egg, salt and pepper.
Add in the chopped sun dried tomatoes, black olives and feta cheese.
Stir it all together. I use my hands but feel free to use a spoon, make sure everything comes together in a batter.
Wet your hands with cold water and roll the mince batter into round meatballs. Place on a cooking tray, space apart.
Oven cook for 10 mins in the middle of the oven 180 °C fan (360 °F).
If using a frying pan, add some butter in the bottom of the pan and fry the meatballs on all sides until golden in colour.
