Found tomatoes and an iceberg lettuce in the fridge, soup or bin?

[Fluffycloudland77]

It's still fresh but is it worth putting the lettuce into the soup?

Soup so far will be parsnips, carrots, onions, one rasher of bacon! and red lentils.

No to the lettuce, yes to the tomatoes, although tinned tomatoes would be nicer.

salad? Soup and salad?
