You may not need 3/4 cup yogurt for the dough - depending upon how watery your yogurt is. Add 1/2 cup first and see if it is pulling the dough together, if not, add a little more. However, if the dough gets messy, add extra flour.
I divided the dough into two parts for the ease of handling. You can do it all together and cut into 8 pieces.
What you use in the rolls is totally upto you! You can play with the variety as you like it...
