Find an on plan food that you really love and keep it in stock. For me it was cooked, crispy chicken wings. I would buy a family pack, cook them and keep them in a bag in the freezer. Could be a special cheese, or even cheese whisps or pork rinds.
Whenever you have a craving or any kind of hunger allow yourself this food. Even if you wind up bingeing, at least you would be on plan. Make up for overeating with a fasting day and no harm done.
