Cooking time: 1-1/4 hours Oven temperature: 160 °C (325°F)

Grease a frying pan lightly and fry lamb until browned on each side but not cooked through. Place each chop or steak on a 25 cm (10 inch) square of foil. Drain fat from pan, add butter, onion and garlic and fry gently until onion is soft. Spoon on top of meat, leaving butter in pan. Place 2 slices of potato on each chop and brush with this butter. Top with slices of tomato and sprinkle lightly with oregano or rigani. Finish with a slice of cheese on top and fold foil, using double folds to seal each package completely. Place close together in a baking dish (cheese uppermost) and cook in a moderately slow oven for 1-1/2 hours.

Serve packages directly onto individual plates. Accompany with a tossed green salad.
