After the sandwich halves have baked, add sauerkraut and russian dressing to the sandwich. I love sauerkraut and the dressing I make is pretty awesome, too. Use a bottled russian or 1000 island dressing if you prefer, but I like to make my own.
My russian dressing contains all or some of the following:
– Mayo/greek yogurt (whatever I have)
– Hot sauce
– Garlic powder
– Onion powder
– Whatever else I feel like using, just make it taste good.
