Preheat oven to 180ºC.
Peel and roughly chop the onion, then add to a food processor or blender along with all the remaining falafel ingredients (with the exception of the sesame seeds). Blend until smooth. You may need to scrape down the sides a few times to loosen away any stuck pieces.
Line a tray with a bit of parchment paper, then divide the mixture into roughly 9 falafel using an ice cream scoop. Sprinkle over a few sesame seeds, then bake for 25-35 minutes or until golden.
To make the hummus, add the wet ingredients to the blender first, followed by the chickpeas, then season with a little pepper and cumin seeds. This helps the hummus to blend much smoother. Blend until smooth and creamy.
Serve the falafel and hummus on warm flatbread, and sprinkle over a little coriander and a little iceberg lettuce.
