It's hot here in MI too! I serve this often, always a hit!
Package broccoli slaw (Mann's brand here) in produce dept.
Cooked and cooled coarse cut chicken breast meat
Red grapes
Cashew nuts (I use salted)
Bottled slaw dressing, I use Marzetti's light or a poppy seed
Combine in desired quantities to taste. Chill and serve with a roll or muffin. Popular with women also. Even my husband loves this, and he's a "meat eater"! Enjoy!
