SHOESTRING POTATO TUNA SALAD

This recipe is from one of my late mother-in-law's co-workers around 40 years ago.

1 cup grated raw carrot
1 cup finely chopped celery
1/4 cup finely chopped onion
1 can (9-oz) tuna, drained and flaked
Mayo-style salad dressing
1 large can shoestring potatoes
lettuce leaves
tomato wedges

In a mixing bowl, combine the carrot, celery, onion, and tuna. Add enough salad dressing to moisten. Put into a bowl with a lid, cover and chill well. Just before serving, stir in the shoestring potatoes. Serve on individual salad places by placing a scoop of the salad on a lettuce leaf and garnishing with a tomato wedge.
