In a large mixing bowl, dissolve the yeast in warm water and let it sit for 5–10 minutes until foamy.
Add flour and salt to the bowl and mix until a shaggy dough forms.
Knead the dough for 8–10 minutes by hand or 5–6 minutes with a mixer until smooth and elastic.
Cover the dough and let it rise in a warm spot for 1 to 1.5 hours, or until doubled in size.
Punch down the dough and divide it into 8–10 equal pieces.
Flatten each piece into a round disc and place a spoonful of cheese in the center. Fold the dough around the filling and pinch to seal.
Place the filled dough balls seam-side down on a parchment-lined baking tray. Cover and let rise for 20–30 minutes.
Preheat the oven to 200°C (390°F).
Bake for 18–22 minutes, or until golden brown on top.
Let cool slightly before serving. Serve warm to enjoy the melted cheese center.
