What's your favorite sandwich?

I think we need to differentiate between sandwich and sub,homemade or bought hot or cold. Whataburger makes a kick *** chicken sandwich.Homemade I like a couple slices of good ham a slice of american cheese and lettuce tomato and onion with mustard for a cold sandwich or a grilled cheese with bacon for a hot one. And who couldnt love a fried bologna on toast? If I was in Chicago there used to be a place called Blue Ribbon Pizzareria on Halsted in Harvey that made a sliced beef with grilled peppers that i think about now 40 years later. it was that good. Hungry now gotta go.
