Going to post the BEST meatball sauce recipe ever - it's not the meatballs, make them however you like, but the sauce.

Meatballs -
500g mince
1 cup breadcrumbs
1 egg
1 onion, diced
parsley, salt & pepper, a teaspoon of curry powder

Mix, roll, bake at 180 for 30 minutes. Stir / roll them, pour sauce over & back in the oven for another 15 - 20 minutes.

Sauce -
1/2 cup water
1/2 cup tomato sauce
3 tablespoons of fruit chutney
3 tablespoons vinegar
1/4 cup brown sugar
2 tablespoons worcestershire sauce

Mix all ingredients in saucepan over medium heat until sugar is dissolved. Pour over meatballs as above.

When cooked, use sauce as a dipping sauce.

* amounts are approximate - I have made this so many times I can't remember what the original amounts are but it's something like this (this is how we like it). You could tweak them to taste.
