400 g feta cheese
A drizzle extra-virgin olive oil
Black pepper, to taste
Prepare two sheets of parchment paper measuring about 30 cm in length.
Arrange a 200 g block of feta cheese on each. Arrange 4-6 onions on each and add a drizzle of oil and some freshly ground black pepper.
Close the sheet of parchment paper around the feta in order to create a papillote.
Place on a baking tray and cook at 210 °C for 20 minutes.
Once ready, open the papillote and serve immediately.
