Sweet Potato Cheeseburger Pizza--Ver II

Ok, so this is a variation on my Crazy Sweet Potato Cheeseburger Pizza, and I totally got it perfect this time.  First time was great, this time perfect.....And then my teen refused to eat another sweet potato--ever--again.  And as far as I'm concerned, paleo with teens is hard enough, heck, paleo for any unwilling party is challenging enough.  No need to shove foods they hate down their throats.  That is a war that cannot be won.  Instead, you gotta win them over with foods they love.  And my kid does not love sweet potato, so I'm going to have to take a break from them for a while.  So much for this idea.  S'alright.  Next week, I will try again with a different base (since this pizza top is too perfect for forget).  But for now, and for those of you who don't want to eat nuts or excessive cheese, or are just cauliflowered-out, this base is a great alternative.  Heck, this topping is so good that you could leave the cheese off altogether and it just becomes Hamburger Pizza.  So here's the recipe:

The Sauce:

1 5-oz can tomato paste

1/2 tsp garlic powder

1/2 tsp onion powder

1 tsp italian seasoning

1 tsp honey

2 tsp balsamic vinegar

splash of water, to thin down

Meat Mixture:

1 1/2 - 2 lbs ground beef

2 tsp garlic powder

2 tsp chipotle powder

1/2 large spanish onion

Pizza Base:

3 large sweet potatoes

1/2 cup tapioca starch

1/2 cup coconut flour

1 egg

1 cup cheddar cheese, grated

Chop and boil your sweet potatoes (don't bother peeling).  Preheat oven to 450 degrees.  When sweet potato is soft, drain and  puree with other base ingredients.  Carefully roll out between 2 pieces of parchment paper and transfer to pie plate.  I didn't bother leaving the parchment under the base--I was using a perforated pizza pan, but it did stick to the pan.  You may want to leave the parchment under the base.  Bake for 17 minutes, until set and beginning to slightly brown on bottom.

Once pizza base is in the oven, brown your beef with all the meat mixture ingredients.  Mix up all your ingredients for the sauce in a small bowl.  When base is set, remove from oven and turn oven up to broil, carefully moving the rack to its highest setting.  Spread the base with the sauce, top with meat mixture, top with cheese and broil until the cheese is melted and it begins to brown a bit.  Remove and let it sit for about 5 minutes (this helps loosen the base from the pan)
