I have deviled eggs in the fridge, they're great! I do have pepperami's for at work and you can't go wrong with ham, cheese and mayo wrapped up in a lettuce leaf.
Fridge raiders have sugar if memory serves me right, most pre-cooked chicken things do. All that stuff at Tesco, Asda etc, all cooked with sugar water to aid browning. Be very careful with ready to eat chicken items.
