Not a sandwich but a had a lovely Morrisons meat feast sub last week.Prosciutto cotto, chorizo, salami, vine ripened tomato, mozzarella, wild rocket, mayonnaise and tomato and basil sauce in a herb topped sub roll.
My favourite sandwich is still tuna and cucumber, from Tesco as it's my local store. Not so much mayonnaise it's offensive either. Plain and simple! Or a classic BLT from Tesco.
I really dislike tuna crunch. Get that onion outta ma sandwich!
