Blue Cheese & Brussel Sprouts Quiche

• Melt the butter in a frying pan over medium-high heat. Fry the onion for 8 - 10 minutes, covered, stirring regularly.

Tip: remove from the pan and set aside to cool before adding it to the egg.

• Meanwhile, grease an oven dish with butter or oil.
• Transfer the puff pastry to the dish and use a fork to pierce holes across the surface.
• Par-bake the puff pastry in the oven for 4 - 5 minutes.
