Metaphor in my muesli

This morning I opened a pack of Trumps muesli, which had been gifted to me from a relative who is given them in her retirement home but doesn't eat muesli

I thought I could look beyond the name, which probably has little to do with the contentious figure.

Toasted muesli isn't normally my thing but free food is good food, right?

Then in the first mouthful I bit into a hardened piece of orange-coloured fruit that proved unpalatable.

The metaphor seemed too rich not to share it here.
