set a 10 inch skillet over medium high heat, add half the cauliflower rice, add a Tablespoon of water, cover and cook for 5 minutes
remove the cover and cook and stir for 5 more minutes
scrape into a strainer set over a bowl
repeat with remaining cauliflower
add it to the strainer and let the lot sit for 15 minutes to drain and cool, stir around occasionally to cool it down and get more water out
pre-heat the over to 400˚ and line two baking sheets with parchment paper OR silpat sheets
pour the cauliflower on a clean dish towel and twist it up to squeeze out excess water, be careful it can still be hot in spots
put the cauliflower in a fresh bowl and add the egg and cheese and mix with your hands
measure out scant 1/3 cup portions on to the lined baking sheets
flatten into 3 1/2-4 inch circles
bake for 12-15 minutes on the first side, then flip them over and bake again for 10 minutes or until the tortillas are flexible but not burned
cool 10-15 minute before serving, these can be made in advance and reheated to serve
