This has been our go-to tailgate sandwich for 3 years now. My husband requests this often and I don't mind at all. I roast my own peppers, add pesto and tomato slices.
I loved this! I added caramelized onions and made my own balsamic vinaigrette. I also used a roasted garlic loaf bread from a local bakery. I chilled it overnight, next I'll try it grilled.
