I agree. Sandwiches are a member of “misery foods”. Especially cold ones.
Can they be good? Yes. But equally, there is usually a more appealing alternative available. Unless you’re in a place of misery.
Eg:
- a small airport.
- a hospital late at night.
- pret-a-manger
- rural train station






Iirc, It was a national problem. Not just Tesco.
Nobody in the supply chain was being overly cautious about what their suppliers were providing them. Resulting in horse meat being found in loads of places.
