Ingredients (makes 4 main servings or 6-8 sides)
- 6 tbsp extra virgin olive oil, divided (90 ml)
- 1 small red onion (60 g/ 2.1 oz)
- 1 large zucchini (250 g/ 8.8 oz)
- 1 small red bell pepper (74 g/ 2.6 oz)
- 1/2 small head broccoli (200 g/ 7.1 oz)
- 1/2 cauliflower (225 g/ 8 oz)
- 1/2 tsp sea salt
- 1/4 tsp black pepper
- 1 package halloumi cheese, cubed (250 g/ 8.8 oz)
- 1/2 cup mixed, pitted olives (50 g/ 1.8 oz)
- 12 cherry tomatoes (140 g/ 5 oz)
- 1/3 cup loosely packed basil leaves, torn
- 2 tbsp fresh lemon juice (30 ml)
Instructions
- Preheat oven to 200 °C/ 400 °F (conventional), or 180 °C/ 355 °F (fan assisted). To prepare the vegetables, cut the zucchini into small (about 2.5 cm/ 1 inch) rounds. Cut the onion into wedges. Chop the pepper into thick strips.
  
 
- Cut the cauliflower and broccoli into smaller florets. Smaller pieces are better as they will cook faster and more evenly.
- Add to a heavy baking tray, and toss with 3 tablespoons of the olive oil, salt and pepper.
  
 
- Bake for 15 minutes, stir, and then return to the oven for another 10 to 15 minutes.
 
- Cut the halloumi into cubes, and scatter across the vegetables, along with the olives and cherry tomatoes.
 
- Return to the oven for another 10-15 minutes or until the halloumi is starting to brown.
  
 
- Toss with fresh basil, lemon juice and the remaining 3 tablespoons of olive oil.
  
 
- Serve immediately, or store in the fridge for up to 5 days. Reheat in the oven or microwave before serving. Cold halloumi is very chewy and always needs to be reheated.
