Preparation / Directions:
1. Peel and core apples; cut into bite-size pieces. Sprinkle apples with lemon juice to prevent browning. 2. Combine apples, celery, grapes, and walnuts in a salad bowl; toss lightly. 3. Blend mayonnaise and salt; gently fold into fruit mixture. Cover; chill until serving time. 4. Arrange lettuce leaves on individual salad plates. Fold marshmallows into fruit mixture. Spoon salad over lettuce.
VARIATION: For a tropical twist, add 1/4 cup shredded coconut after adding the mayonnaise mixture in step 3.
