Preheat oven to 180C (200C if you are making the roast vegetable salad at the same time). In a bowl, combine mince, onion, egg, breadcrumbs, herbs, garlic and pepper. Mix together thoroughly (this is easiest with clean bare hands).
Roll into 12 evenly-sized balls and fry in oil on fairly high heat to brown, preferably in a shallow, oven-safe pan.
Drain oil from pan and discard. Pour pasta sauce over the meatballs and put in the oven to cook through (about 20 minutes). This is a good time to cook your pasta.
Serve over pasta sprinkled with extra chopped herbs if desired.
