1 x 660 g jar chickpeas (or 500 g cooked chickpeas)
1 tsp finely chopped garlic
100 g tahini
1 tbsp extra virgin olive oil
1/2 tsp sea salt flakes (or more to taste)
80 ml freshly squeezed lemon juice
A little ice-cold water, to loosen
Directions
Preheat the oven to 200C/400F. Drain the canned chickpeas and toss with the potatoes, cauliflower, olive oil, cornflour and all the spices, salt, pepper, oregano and sesame seeds.
Spread on a tray and roast until deeply golden and crisp, about 30-40 minutes, turning once (or air-fry in two batches for full crispiness).
For the hummus, blend the jarred chickpeas, garlic, tahini, extra virgin olive oil, salt and lemon juice until smooth, loosening with a little ice-cold water as needed.
Spread the hummus over a plate and pile the spiced roasted vegetables and chickpeas on top.
