This was simply delishious. My spouse was poo-pooing it as I was making it, uncertain that a cauliflower-based crust would appeal, but once done he raved about the dish overall (he ate 1/2 of the pie!). My only variation was to add 3/4 of a cup of milk vs a full cup & it baked up firm yet moist. The cauliflower crust didn't "stand out" as a traditional crust would, but it served its purpose: to keep ingredients in and calories out.
What's left (which isn't much) will reheat as a fine breakfast treat.
