An irresistibly good, great big sandwich. Easy to make ahead, perfect for parties, picnics and potlucks.
Preheat the oven to 400 degrees F. Slice the loaf of bread in half down the middle from end to end. On one half of the bread, spread the pesto. On the other half of the bread, spread the Italian Dressing. On the pesto side, layer half of the ham, half of the turkey, half of the salami, and half of the cheese. Then, repeat the layers with the remaining meat and cheese. On the Italian Dressing side, layer the roasted red peppers and the peperoncini peppers. Sprinkle with Italian Seasoning. Place the two halves together, wrap tightly with foil, and place on a baking sheet. Transfer the baking sheet with the wrapped sandwich to the oven and bake for 15 minutes, or until the sandwich is heated through and the cheese is melted. Unwrap the sandwich and slice into sixths. Serve immediately.
