Ingredients (makes 4 main servings or 6-8 sides)

  • 6 tbsp extra virgin olive oil, divided (90 ml ml)
  • 1 small red onion (60 g/ 2.1 oz)
  • 1 large zucchini (250 g/ 8.8 oz)
  • 1 small red bel 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)


  1. 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.

  8. 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. Low-Carb Roasted Vegetable & Halloumi Tray Bake

Excellent side dish!  I will do this one a lot!!!


This was amazing!  We used feta instead of halloumi (which is very expensive where I live).  Wonderful mix of flavors and very easy to prepare.


Thank you Krissie, I'm happy you enjoyed!
