Wow, @coquicoin, what a pro sandwich eater you are. They all sound absolutely delicious and I can see why you have such vivid and wonderful memories, and still enjoying sandwiches.
For me, I was never a happy sandwich eater girl even though this is what I took to school for lunch everyday fro 12 years. My fillings were very simple; Vegemite, peanut past, dates, sultanas, cheese etc.
Hot savoury mince buns were my favourite from the canteen is a favourite memory of my primary school days.
Now as an adult I have been found to be wheat intolerant which explained why I did not eat my crusts.
All very sad as I leave all bread gluten and gluten free alone. What I miss out on. 😊🧡
