If you eat enough kiwis with skin, tarantula abdomens start to look like something tasty.

I read that online, I trained myself to eat whole Kiwis and lo and behold: It is true!

Our brains are so wonderfully strange!

Possibly not an illusion: https://en.wikipedia.org/wiki/Arachnids_as_food

That was interesting other than the golden orb weaver, all the other spider species noted as edible are tarantula.

I assume because of their size relative to other species?

People in the Amazon do eat tarantulas. They do roast them over an open flame first though to burn off the hairs as they can be harmful and irritating.
