Ingredients
Method
1.Preheat oven to hot, 200°C (180°C fan-forced).
2.Line a 20cm x 30cm slice pan with pastry sheets, joining and trimming to fit. Prick base all over with a fork. Bake for 8-10 minutes.
3.Remove from oven and cover with a clean tea towel, pressing down to flatten puffed base. Brush with a little of the egg. Bake for a further 4-5 minutes, or until golden.
4.Arrange onion, asparagus and ham evenly over pastry. Pour egg over, gently tilting the pan to fill gaps and corners. Bake for 5-10 minutes, or until the egg is just set. Serve.
Brushing par-baked pastry with egg helps to seal the surface, and preventing the base from going soggy when filling is added.
