Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.
Microwave cauliflower for 3 minutes; stir and microwave additional 2 minutes. Let cool.
Put cauliflower in dish towel and squeeze out as much moisture as possible.
In a bowl, combine the cauliflower with the Parmesan, oregano, salt, garlic powder and eggs.
Drop by tablespoons on baking sheet and flatten into small circles.
Bake for 10 minutes and turn over. Bake an additional 7-10 minutes.
Cool on wire rack. Trim each piece with scissors for a nice, round appearance.

Notes
You can also make Cauliflower bites by dropping the cauliflower to 2 cups and leaving out the Parmesan cheese. Change the seasonings if you like. And make a larger version (1/4 cup of mixture) to use instead of tortillas.
