In microwave safe bowl place mozzarella cheese and cream cheese. Microwave for 30 seconds to 1 minute on high. Take out and stir. Put back in microwave for 30 seconds, then stir again. Depending on your microwave you will may need an additional 30-60 seconds until all melted and combined.
While the cheese is in the microwave mix together the egg, almond flour, salt and rosemary (if using). Take cheese out of microwave and stir in egg and almond flour mixture until it forms into a sticky ball of dough.
Mix melted cheese mixture and almond flour mixture until FULLY combined. You may use your hands at this point, but it will be messy.
Place a sheet of parchment paper on counter and drizzle with a tiny bit of olive oil. Place ball of dough in middle of bottom parchment paper. Wet your clean hands and press the ball of dough with your damp hands into a pizza shape. I like a rectangle shape for this pizza for ease of serving.
Oil a second sheet of parchment paper and place face down on top. Flatten down with your palm, then with a rolling pin (or something heavy and round) roll out dough into a pizza rectangle in between the two sheets of parchment paper.
When you have your desired thickness and shape peel off the TOP sheet of parchment paper. I like mine super thin, but be careful it doesn’t stick. You will be baking this pizza on the bottom sheet of parchment paper.
