Cauliflower Crust Hawaiian Pizza

Ok what is the trick to making the crust so that it doesn't fall apart? Every time I've made it, you can't pick it up like a pizza.

The key is is to pulse cauliflower in food processor until it looks like rice. Put cauliflower in microwave for 8 minutes to dry it out (don’t add any water or other liquid). Let it cool. Then, grease pie pan with cooking spray or butter. Spread the cauliflower mixture evenly in the pan. Bake until the edges are slightly browned. Take it out. Move the rack to broil position, turn on broiler. Stick the crust back in to broil for 2-3 minutes or until the top is golden brown. This is worth the extra step to make sure the crust is crispy and not mushy.
Finally, add your ingredients and bake until cheese has melted!
Hope this helps!
