To make the bagels, into a bowl add the flour, yoghurt, baking powder and salt.
Mix to form a soft dough.
You may need to add a drop of water to help bind.
Roll these into 4 small rounds and, using your finger, make a hole in the center of each.
Preheat your oven to 200C/180C fan.
Egg wash the bagels and sprinkle the sesame and poppy seeds over the top.
Bake in the preheated oven for 12-15 minutes or until golden brown all over.
Remove and allow to cool.
Once cold, cut in half, spread each half with tomato sauce, top with cheese and pepperoni slices and pop back into the oven for 5 minutes.
Enjoy warm or cold the next day.
