Don't do it myself but fish finger sarnie and scrambled egg sarnies are normal in my house. But then again the wife and kids like toast done where it just starts to get yellow and 1 side only. To me toast should be brown and both sides.
Myself am partial to stew sarnies. Or cheese and salt&vinegar crisps. McCoys preferably.
Worked with a guy who used to have Ham and Raspberry jam sarnies. Can recall my brothers eating apple and mars bar sandwiches.
Being realistic how is a fish finger sarnie any different than McDonalds Fillet O Fish.
At my old work we used to have Fat Friday sandwiches and mine was doorstop bread with bacon, sausage, cheese, brown sauce and beans... it was a messy bugger but man did it set you up for the day!
When I was younger my fav was the two tier breakfast club tower.
bread underneath, sausage and egg on tier one, separated by a slice of toast coated in brown sauce , bacon and saladwith mayo on top under another slice of bread .
Epic sandwich!
Now I tend to avoid bread as much as possible, piles on the pounds!
Prefer wraps if I have to have something, the toasted cheese tortilla wrap with bacon and sausage is a personal recipe!
