2 cups iceberg lettuce, shredded, well-drained and dry
2 navel oranges
2 golden delicious apples, unpeeled and thinly sliced
2 cups green seedless grapes
13 cup mayonnaise
13 cup sour cream
1 cup mild cheddar cheese, shredded (4 oz)
Place the shredded lettuce in a deep 2-quart glass serving bowl. Peel and section the oranges over a bowl, reserving the juice. Combine apple slices and orange juice; toss to coat. Layer apple slices over the lettuce; top with the orange sections and grapes. Combine mayonnaise and sour cream in a small bowl; stir well. Spread mayonnaise mixture over salad, sealing to the edge of the bowl. Sprinkle with cheese. Cover and chill at least 8 hours.
