my favorite one is my coriander and chilli lamb meatballs with a spicy tomato sauce. I have made it for a few guests now too and they couldnt get enough of it. It is quite spicy, but you can cool it down with the yoghurt as suggested.
plus the ultimate burger recipe is heaven, and filling just on it's own.
Mix turkey & pork mince together, add a red chilli, salt & pepper, a couple of crushed garlic cloves & some mixed herbs & fresh chives & little bit a cayenne pepper (not a lot though), I them wrap each burger round a mini babybel & grill. The cheese melts in the middle - they are loverly.
