OK. Here we go....
Pork shoulder smoked on grill or slow roasted.
Roll (A seeded one)
Garlic, mushrooms and shallots (saute in oil then deglaze with white wine).
Cheese (but sharp provolone is always used on pork so I think I want something gooey. Any suggestions?)
And the secret ingredient is: ROASTED RED PEPPER SAUCE.
And I'm thinking of adding coleslaw but I don't think that would work.
I might also try a variation where I don't add the roasted red pepper sauce but I had really spicy baked beans to the top. I'm note sure if I've ever seen baked beans on a sandwich.
