Cut the phyllo sheets into 30cm squares and make 8 equal stacks of 3 phyllo sheets, brushing each sheet with olive oil.

Divide the cubes of lamb, vegetables and cheese among the stacks, placing them in the center of the squares; top each with 2 tomato slices, sprinkle with oregano and season with pepper and sprinkle with cheese. Gather the edges of the dough together over the filling to form 4 pouches. Tie loosely with kitchen string and brush lightly with oil. Put the pouches into the prepared dish, cover loosely with aluminum foil or roll into another pouch of baking paper to avoid falling apart and bake for about 40minutes. Serve immediately.
