[Sundae]

The burger, as constructed, contained onion rings.
I had to deconstruct it anyway to get rid of the raw tomato, so I took them out to eat separately. They were recognisable as onion rings. Rings made of onion.

Then, as a little extra offering I had some nuggety execrations.
Failed onion rings I think. They were definitely onion in origin. Too mutant to eat. I was going to take them home as unlucky charms, but I had my new voucher-bought clothes with me.
