So many good ones to choose from, not so sure of bad ones.
Penutbutter cookies made with coffee and chocolate chips
A friend worked at a Subway and made me a tuna sandwich with lettuce, tomato, and the "fixings", but also added roast beef. That was good.
I would stop at a sub shop and get a meatball and cheese sub with everything, all the fixing, including pepperoncini and jalapeno peppers. That was a good one.
My all time favorite that I miss so much was a Calzone (Only Cheese, never meats, that would be Stromboli

) from Sal and his wife (Sicilian) from their restaurant.
Still trying to think of bad ... if I think of something I'll have to edit
