First impression, tasted the cauliflower, like a lot of cauliflower substitutes for carbs....ok now with that in mind, this was actually really really good. I didn't bother with cutting out The middles. I just made little round patties and they were perfectly holding together, I put cream cheese on the top and they actually were delicious.
It's the common known trouble of having to rice your cauliflower, a little time consuming, so you can do it yourself or you can buy it already done. But after that, adding the ingredients and patting them out and baking them were fine. That "everything bagel" mixture is incredible, and makes everything taste good !
