Put the minced lamb along with all of the herbs and spices, the egg and the onion (raw) into a food processor and blend into a paste.
Spoon the mixture into a non-stick loaf tin and pat it down. Cover with foil and pop it in the oven at 180°C for around 40 minutes. Remove the foil and then return to the oven for a further 10 minutes.
After removing from the oven, leave to cool for 10-15 minutes. This makes it much easier to carve.
Slice into thin slices and pop it on a pitta bread with your choice of salad.
