Microwave the riced cauliflower (5 minutes) or steam it in a medium pot (7-10 minutes over medium heat), covered
Once the cauliflower is cooked, add the ground flax and coconut flour and stir well.
Add the egg whites, salt and garlic powder, stir to incorporate the eggs
Spray the donut pan with non-stick spray. Divide the mixture to make 8 bagel halves, filling 8 of the donut molds (don't over fill, you want these to be pretty thin - about 2-3 tbs. per mold). Be sure to press down on the mixture, making sure well compacted in the mold
Bake in the oven at 400F for 25 minutes
Take out of the oven and allow to cool for 5 minutes. Flip the bagels (I placed a cutting board against the pan and carefully flipped it, keeping the cutting board pressed up against the pan until the pan was completely upside down)
Flip the bagels and place them on a baking sheet to bake for 5 more minutes to brown on the other side. You can spray them with a little non-stick spray and sprinkle them with Everything seasoning at this point.
