To make with a Sandwich Sealer
: Warm the bread in the microwave briefly for about 5 seconds. Stack two pieces of bread and press the outer round down to cut rounds. (Or according to the directions of the sealer if you use a different kind than I have.) Add your fillings, leaving some space around the edges of the bread so the filling doesn't seep out. Put the round back around the bread, then press down with the smaller insert to crimp the edges.
