Chicken salad

Cut cold, boiled chicken into small dice. With two cupfuls of this meat mix a cupful of celery cut into dice. Sprinkle all with salt and pepper. Into three tablespoonfuls of oil stir a tablespoonful of vinegar. Pour this over the chicken and celery and toss until well mixed. Line a chilled bowl with crisp lettuce leaves, fill with the chicken salad and pour mayonnaise dressing over all.
