Burger numbers 4 and 5. Both of these have been made with lamb patties (I seasoned with parsley, pepper, garlic and chilli powders).
4: The Greek
Tzatziki, tabouli, sliced kalamata olives, feta cheese
5: the Tropical Smoke
Smoky BBQ sauce, onions, tomato, grilled pineapple, leafy mix, leg ham, Dutch smoked cheese
For the onions on the tropical smoke:
Dice up a whole brown onion and put into a bowl. I suggest using tinned pineapples in syrup for the grilled pineapple, because the syrup from the tin should be poured into the bowl with the onions. Then stick it on a hot pan, and let it reduce. The onions will be sweet and pineapple flavoured.
