1) 350 grams of spicy sausage;
2) 200 grams of creamy cheese;
3) 2 eggs;
4) 2 rolls of puff pastry;
5) 2 medium size potatoes;
6) 2 medium size red onions;
7) Olive oil;
10) Parchment paper;
Lay half of the puff pastry on the parchment paper (which in turn was laid on a baking tin), making sure that the edges of the dough adhere properly.
Mash the potatoes and put them on the puff pastry, making sure that they are well spread.
Take the skin off the sausages if needed, then cook them in the same pan that you've used for the onions and add a pinch of salt. When the sausages are ready, add them to the potatoes and the onions, spreading them in the same way.
Cover the whole thing with the remaining half of the dough, cutting the redundant edges out.
Crack the egg open and set apart the yolk from the albumen, tossing away this last one. Afterwards, spread the yolk on top of the pie using a cooking brush until it's entirely covered. Put the pie in the oven at 180 °c for 10 minutes, after which you will lower the temperature of the oven to 150 °c for another 15 minutes. Take it out of the oven and let it cool down for 15 mins. Enjoy!
