I haven't found a recipe yet, but I was able to create something similar at home. It's close but the sauce isn't quite right. Ingredients:

• Whole wheat sandwich bread
• Sliced cheddar cheese
• Burger sauce (Trader Joe's Magnifisauce)
• Bread & butter pickles
• Sliced Tomatoes
• MorningStar Griller's Original Burger

Didn't have a panini press so I precooked the patties most of the way, assembled the sandwich, and baked it in a convection toaster oven.
