If using uncooked chickpeas place them in a bowl and soak over night.
Drain the soaked chickpeas.
Preheat the oven to 200 degrees Celsius.
Add all the ingredients for the beetroot falafel to a food processor and mix until you have a fine mixture, with some small pieces left. Don't mix until completely smooth (or almost completely smooth), then the falafel will turn into hummus).
Prepare a baking sheet with parchment paper.
Form equally sized balls (between 16-22 depending on how big you make them), and place on the prepared baking sheet.
Bake in the oven for 25-30 minutes.
Meanwhile make the white bean hummus (you can also swap the white beans for chickpeas if preferred). See note 1 for the recipe.
Place white bean hummus at the bottom of the plates.
Top with beetroot falafel, arugula and buckwheat.
