- Toss the onion, beetroot and peppers in a little oil and air fry at 180°C for 15 minutes, or until the beetroot is tender.
- Meanwhile, in a bowl, combine the boiling water and stock cube. Add the couscous and cover with a plate for 5–10 minutes. All the water should get absorbed.
- Once the beetroot is tender, add the tomatoes, olives and halloumi and air fry for a further 5 minutes, or until the halloumi is nicely browned.
- Serve the couscous with the roasted veg on top. Garnish with the chopped basil.
