Put cauliflower rice in microwave for 2 minutes; stir and return to microwave for 2 additional minutes. Let cauliflower rice cool (can be put in refrigerator overnight). Squeeze out as much water as possible. I put the cauliflower in a dish towel to wring out the water. Put drained cauliflower in mixing bowl.
Heat oven to 350 degrees Fahrenheit. Line rimmed baking sheet with parchment paper.
Add all other ingredients to cauliflower and mix well. The mixture will be quite liquid. Drop by tablespoon measures onto baking sheet and pat flat with spoon. The mounds can be relatively close together because they won't "rise". However, the egg will seep out as they cook. We will deal with that later.
Put in oven for 10 minutes; remove from oven and flip over (you may have to cut the cooked egg seepage to do this - but not to worry, we will make them beautiful later. Bake for another 7-10 minutes.
Remove from oven and put on cooling rack. When they are cooled, use kitchen scissors to trim into nice circles.
Beautiful! Good job! They are ready to eat. You can top with Parmesan, Gruyere or aged cheddar cheese and reheat when you serve the bites, if you want.
