I quite often saute onion, garlic and sundried tomato before adding them. I use a bit of tomato sauce to bind because I find egg gives quite a strong flavour. I always use copious amounts of dried italian herbs (yum) and I glaze with a mix of tomato and soy sauce before often baking.
Tonight i made lamb meatballs and after glazing I sprinkled roast lamb seasoning over the top - so tasty.
