Wow, this is making me hungry. I usually just boil some chicken or even get a whole chicken that is already cooked. I dice some celery and throw some salt, pepper, a tiny bit of garlic salt and Miracle Whip. Maybe I need to write down my amounts. I have a tendency to throw them together.
I've never thought of apples, grapes or walnuts. I will have to look into that. Mmmmmmm!
