Chop rosemary into fine pieces.
Put flour, cheese, rosemary, salt and pepper into the bowl of a food processor.
Cut the softened butter into pieces and add to the dry mixture.
Pulse a few times, then mix until the dough comes together. If the dough doesn't start coming together fairly quickly, add about a teaspoon of water and mix again.
Put the dough out onto a piece of plastic wrap and shape into a smooth round shape without major cracks.
Wrap the dough in plastic wrap and refrigerate for 1 hour.
Preheat oven to 350 degrees.
Place the dough on a sheet of waxed paper and cover with another piece of waxed paper, then roll out into a flat disk that is about 1/4" thick.
Cut dough into any shape you like, using a cookie cutter.
Place an herb leaf on top of each cracker. I used sage, rosemary and parsley leaves.
Cover with a piece of waxed paper, and gently roll over crackers with a rolling pin to press the herbs into the dough.
Place crackers on a baking sheet and bake for 10-15 minutes or until the edges start to turn light golden.
