In a medium microwave safe bowl, add the mozzarella cheese and light cream cheese. Microwave on high for 1 minute – stir and microwave another 30 seconds.
Add this mixture into the bowl of a food processor. Mix for about 30 seconds.
Add the egg and mix again for about 10 seconds.
Add the almond flour, coconut flour, baking soda and salt to the processor and mix for 20 seconds.
Scrape the roll dough into the center of a piece of plastic wrap and flatten it slightly. It should look like a thick disk.
Wrap the dough up and place in the refrigerator while the oven heats.
Preheat the oven to 400 F. Prepare a baking sheet with parchment paper. Set aside.
When the oven is ready, remove the dough from the refrigerator and using a sharp knife, cut the dough into 8 equal pieces. Roll each piece into a ball and place on the baking sheet.
Sprinkle lightly with sesame seeds.
Bake for 15 minutes. Remove from the oven and let cool on a wire rack.
Notes
20 seconds is all you'll need for a quick mix in the food processor.
Chill the dough while the oven is heating so it'll be easier to handle.
