Cut 2 peppers into slices.

Cut the third pepper along the top, removing the seeds and core. This will be the octopus body.

Place the body, open-side down, onto a plate of hummus; add eight pepper slices around it as tentacles.

Slice olives. Dab a bit of hummus onto 2 olive slices and stick them to the pepper for eyes.

Serve octopus with remaining pepper slices and olives on the side.
