1 x 400g can chickpea , don't drain
1 tbsp tahini paste
1 fat garlic clove , chopped
3 tbsp 0% fat Greek yogurt
good squeeze lemon juice

Drain the chickpeas into a sieve set over a bowl or jug to catch the liquid. Tip the chickpeas, tahini, garlic and yogurt into a food processor or blender and whizz to smooth. 

Whizz in a tbsp of the chickpea liquid at a time until you have a nice consistency, then scrape into a bowl.

Stir in a squeeze of lemon juice and season to taste.
