Preheat the oven to Gas Mark 7.
Arrange the red onion, peppers, baby plum tomatoes, garlic, oregano on a large baking tray and roast for 30 minutes.
Remove the peppers and transfer to a bowl and cover it with cling film.
Lower the Oven to Gas Mark 6 and continue to bake the onions and garlic for a further 10 minutes, then remove the tray from the oven.
Remove the peppers from the bowl, peel away the skin, deseed and chop into 1 inch slices.
Squeeze the garlic out of the skins and keep aside.
Add all the veg and roasted tomatoes to a large bowl.
Heat the oil in a frying pan and add the courgette. Heat over a high heat for 5 - 6 minutes.
Add the courgettes to the veg bowl.
Add the Ciabatta to the same pan as the ones used for the courgettes, season, add tomato puree and crisp for 3-4 minutes. Remove the bread and set aside.
Lower heat and add more oil to the pan, along with the garlic and capers. Squish the garlic with a fork. Add the vinegar and lemon juice and pour over the vegetables.
Add the Halloumi pieces to the pan and cook until softened and slightly browned. (1 - 2 minutes each side) Don't over cook because it becomes really squeaky!
Add the bread to the veg bowl, along with the rocket and Halloumi. Taste and adjust the seasoning.
Serve warm with Greek Yoghurt and a drizzle of honey if you like!
