Preheat the oven to 170°C (340°F).
Line a baking tray with parchment paper.
In a large bowl, mix the flour, salt (with herbs or regular), garlic powder, and baking powder.
Add the Greek yogurt, parmesan, and minced garlic.
Mix until a dough forms.
Knead briefly on a lightly floured surface until smooth.
Do not add too much flour.
Divide the dough into 6–8 equal portions and shape them into round buns.
Place the buns on the baking tray, brush with egg wash, and sprinkle with toppings if using.
Bake for 25–30 minutes, until golden and puffed.
Allow to cool for at least 15 minutes before slicing.
