This is a traditional 'Sunday Lunch' dish. The orzo (a kind of pasta that is shaped like large grains of rice) cooks in the liquid released by the lamb and tomato and becomes very tasty. Many make it with a cut of beef suitable for roasting, cut into large pieces, or even with chicken pieces.
03In a large saucepan, bring plenty of water to the boil, salt generously and boil the orzo pasta for 8 minutes. Remove and drain - retain a cup of the cooking water. Add the pasta to the lamb casserole and give everything a stir to distribute orzo throughout the pan.
04Increase heat to 400F (200C) and continue to bake another 15-20 minutes, or until pasta is fully cooked and has absorbed most of the liquid in the pan (it should still be fairly 'juicy' - not dry). If the pasta is too dry, stir in enough of the pasta cooking water you've retained to keep it saucy.
05Have lots of freshly-grated parmesan or kefalotiri cheese to sprinkle over pasta at table.
