I came across an oversized salad suggestion in Hannaford's Fresh magazine for a Waldorf type of salad. It was too big for us, and still used mayonnaise, which I just cannot eat. So I changed it quite a bit and have shared it below. Still, they gave me the basic plan, so they deserve the credit. See their version at the link above!
1/2 c Greek yogurt
1 T fresh lemon juice
2 T grated Parmesan cheese
3/4 t garlic powder
1/4 t freshly ground black pepper
Milk, added just to thin dressing if desired
1 cups seedless red grapes, halved
1/3 c chopped celery
1/3 c chopped pecans
1/4 c dried cranberries
1 Gala apple, skin on, chopped
1 Granny Smith apple, skin on, chopped
Chopped or baby romaine lettuce
In a glass measuring cup, whisk together the yogurt, lemon juice, cheese, garlic powder, salt, and pepper. Whisk until smooth, adding milk if needed.
In a large bowl, mix the grapes through the apples. Toss with romaine lettuce and dressing.
