Take the dough out of the refrigerator and let it rest for a short time. Preheat oven (electric cooker: 200°C/circulating air: 175°C/gas: see manufacturer). Line a baking tray with baking paper.
Cut the broccoli into very small florets, wash and drain. Peel the onion and cut into strips. Cut the bacon into pieces.
Roll out the dough, fold it over halfway from the short side. Then cut across into 4 strips. Place on a baking tray, press the middle of the strips a little wider, press the ends of the dough together.
Spread the dough with sour cream, leaving a small rim on each. Spread broccoli on top. Season with salt and pepper. Spread bacon and onion over it. Sprinkle with cheese. Bake in a hot oven for about 20 minutes.
Take them out and sprinkle each with 1/2 teaspoon pesto.
