Macedonian Lettuce Salad with Yoghurt

Ingredients

 * 3 sm Cos lettuce; (Little Gem -type)
 * 1 ts Slat
 * 1 8 ounces thick Greek style -yoghurt
 * 1 ts Sugar
 * 1 tb Lemon juice
 * 1 tb Oil; (olive if possible)

Directions

 * 1) Separate the leaves on the lettuce, wash them thoroughly and dry them.
 * 2) Tear each of the bigger leaves in half and arrange in a bowl.
 * 3) Not more than 5 minutes before you're ready to eat, sprinkle the salt over the lettuce and beat the oil, lemon juice and sugar into the yoghurt.
 * 4) Pour the yoghurt over the lettuce and toss gently and serve rapidly.
 * 5) The lettuce will wilt if kept for more than 10 minutes in this dressing, but before then its crispness and the creaminess of the dressing complement each other wonderfully.
