The experiment with the brioche dough to make buns worked! I patted out the dough on a floured counter and cut them out with a big biscuit cutter. I let them rise for about 45 minutes and then baked at 350° for about 25 minutes.
They made excellent panini!
Mayo and dijon mustard, sliced ham, roasted red peppers, and fresh mozzarella.
Simplicity.
