Step 1

Put the lamb into a large bowl and add the oregano, pepper, garlic and oil. Mix well and leave to marinate for 1 hour.

Step 2

Bring the stock to a very gentle simmer in a saucepan.

Step 3

Put the egg yolks and lemon juice into a roomy heatproof bowl and beat well. Reserve.

Step 4

Remove the garlic from the lamb and season the lamb with salt. Heat a frying pan over moderate heat and panfry the lamb for about 4 minutes on each side for medium (pink and juicy on the inside but cooked). Remove from the heat, place on a plate, loosely cover with foil and allow to rest while you cook the vegetables and make the sauce.

Step 5

Bring a large saucepan of salted water to the boil and add the broccoli. Bring back to the boil and boil 3 minutes then add the snowpeas and spinach and boil a further 2 minutes. Drain well.

Step 6

Bring the stock to a rolling boil then remove from the heat. Whisking continually, add the stock slowly to the egg yolk and juice mix. Pour back into the saucepan and place directly over moderate heat and stir until the sauce thickens slightly. Do not boil or it will curdle. Taste and season with salt.

Step 7

Slice the lamb on the diagonal across the grain of the meat. Serve the lamb on the vegetables with the sauce over it and sprinkled with the zest and the rice on the side.
