Nutrition facts(per serving)


  • 120g mushrooms
  • 2 spring onion, sliced
  • 2 tsp olive oil
  • 80g spinach
  • 8 eggs
  • 40g basil pesto – if buying pesto, read the ingredients list and ensure it doesn’t use vegetable oil (olive is best)
  • 80g feta cheese


  1. Preheat the oven to 180°C/350°F/Gas mark 4 or 200°C/400°F/Gas mark 6.
  2. Grease a large muffin tin (or regular muffin tin).
  3. Saute mushrooms and spring onion in olive oil for a few minutes to soften the mushrooms.
  4. Add spinach and wilt.
  5. Set aside to cool.
  6. Whisk the eggs with the pesto.
  7. Portion the veggies evenly between muffin wells. If using a large muffin tray, it will make 1 per serve (4 in total), if using a regular muffin tray you may get 2-3 per serve or 8-12 in total.
  8. Pour in the eggs and top with crumbled feta.
  9. Bake for 15-20 minutes or until golden on top and springy to the touch.


  • Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat and serve.
  • Some brands of cheese (including feta) may contain rennet so are not strictly vegetarian. Check the product you buy uses vegetarian ingredients. Brands vary, it is always important to read labels first.
  • Serve with a crunchy green salad or steamed low calorie non-starchy vegetables.
