Preheat the oven to 200 degrees Celsius; prepare an oven safe baking dish.
Add the mince in a mixing bowl, add the grated onion, egg, herbs and mix through with your hands.
Grease an oven safe baking dish with oil, and use some for your hands as well while rolling the mince into small “bouncy ball” size meatballs.
Arrange in baking dish, set aside.
In a medium sized saucepan, heat the olive oil and sauté the onion, garlic and chilli until soft. Add the tomato cans, set to a simmer and add the herbs, sugar, vinegar and seasoning – stirring while simmering for about 10 minutes.
Cover the meatballs with sauce, and bake for 20 minutes at 200 degrees Celsius, stirring every now and then.
After about 20 minutes, your meat should be cooked through, but if you like to add a bit of colour to the meatballs, you can add a few more minutes on the clock.
Serve hot, with toasted bruschetta.
