Left-Over Chicken Salad

Ok, so last night I made roasted chicken with potatoes and onions, so this is what to do with the left-overs.

1/2 roasted chicken
7-10 green grapes, cut in half
1/2 granny smith apple, diced
1 green onion, diced
1/4 - 1/2 cup mayonnaise
Dash of red wine vinegar
Salt
Pepper

Take the chicken off the bone and dice. Combine with the grapes, apple, and onion. Add mayonnaise (the amount is up to you, depending on how much mayo you like), vinegar, salt and pepper to taste. Chill for at least an hour, and serve on whole wheat rolls.
