All cooked on one tray in the oven, it’s low on carbs, calories and washing up!

Nutrition facts(per serving)


  • ½ large tomato, quartered
  • 1 Portobello mushroom
  • 50g halloumi, cubed
  • ½ tbsp olive oil
  • 2 large free range egg


  1. Preheat the oven to fan forced 180°C/200°C/400°F/Gas mark 6 and line a baking tray with paper.
  2. Place tomato and mushroom on the tray and drizzle with olive oil – season with salt and pepper. Add halloumi onto the tray. Bake for 20 minutes.
  3. Remove the tray from the oven, create a little space, crack the eggs onto the tray and return to the oven for about 5 minutes – until the eggs are cooked to your liking.


  • Some brands of cheese (including halloumi) may contain rennet so are not strictly vegetarian. Check the product you buy uses vegetarian ingredients. Brands vary, so it is always important to read labels first.
