- Preheat the oven to 190°C and lightly oil a 25-cm solid-based pizza tin or a baking tray.
- Put the lamb and pork into a bowl. Add the herbs, then stir in the egg, breadcrumbs, salt, pepper and a good splash of Worcestershire sauce. Mix well together.
- Press the mixture evenly into the pizza tin, or put onto the baking tray and shape into a 25-cm round. Cook the burger in the oven for 15–20 minutes.
- Meanwhile, heat the olive oil in a frying pan. Peel and chop the onion and garlic, add to the oil and fry for 5 minutes, or until soft. Stir in the chilli powder, if using, then remove from the heat.
- Clean the mushrooms. Seed the capsicum and dice it, then slice the tomatoes and mushrooms. Cut the mozzarella into thin slices and grate the Gloucester or Cheddar.
- Remove the burger from the oven and drain off any liquid, if necessary, then increase the oven temperature to 220°C.
- Spread the onion mixture over the burger, add the capsicum, tomatoes and mushrooms, and sprinkle the cheese on top. Bake for 5 minutes, or until the cheese melts.
- Serve in wedges, with crusty bread, salad and tomato sauce or a spicy relish.
Any combination of mince can be used, including chicken or venison. The herb seasoning can also be altered: an all-lamb burger could be seasoned with rosemary and mint; a pork and sausage meat burger or chicken burger with sage and parsley; a venison burger with thyme or oregano. The vegetables can include corn, olives or any other pizza topping you like.
