My lab just loves bananas. She also likes anything that she has stolen, cucumber, lettuce etc that she would normally turn her nose up at.
What does yours like?
Raw brussell sprouts, they go mad for them! And carrots. Sometimes though if someone drops something one of the dogs will eat it for the sake of it just so's no one else can, e.g. my oldest JR ate some red onion that was left on a plate because she'd seen the youngest JR looking at it!
My JRT loves bananna, can smell it from a mile off! Will try anything he can get his paws on, he is such a scavenger. The other likes to eye up the guinea pig food and has a thing for bread with nothing on.
