Roll out premade pizza dough to about 1/8 inch thick, place it on a parchment-lined baking tray, and poke holes all over with a fork.
Slice Manchego cheese into 10 thin pieces (about 1/8 to 1/4 inch thick) and arrange them on the dough.
Thinly slice 6 washed and dried button mushrooms, then scatter them evenly over the cheese.
Pit and chop 6 dates, then sprinkle the pieces evenly over the mushrooms.
Drizzle the flatbread with extra virgin olive oil and season with sea salt and freshly cracked black pepper.
Chop a handful of fresh parsley and 1 sprig of rosemary, then spread them evenly over the flatbread.
Bake in a preheated oven at 210°C (425°F) on the bake + broil setting for 14–16 minutes, until golden.
Cut the flatbread into 2 x 6-inch pieces, serve, and enjoy!
