Pre-heat oven to 350F.
In a bowl, transfer the all-purpose flour, plain greek yogurt, baking powder & salt. Using a sturdy spoon, mix until it starts to come together then use your hands to further gather the mixture to form into a dough. Transfer in a floured surface.
Divide the Dough: Divide the dough into 6 equal portions or as close sizes as possible.
Stuffed: Flatten the dough and stuff with cream cheese & 1 sliced jalapeno peppers. Roll into a ball, pinch the sides to seal the dough.
Top with Cheese: Brush the top with eggwash. Roll in the grated cheese or sprinkle cheese on top. Put 1 sliced jalapeno on top and sprinkle with Everything but the Bagel seasoning ( if using).
Bake in the middle rack for 30 minutes, rotating the baking sheet midway through baking ( at 15 minutes time). Remove from the oven.
Let cool slighlty before serving. Cooling will enhance the texture of the bread, so this is a MUST.
