Pear & Sweet Potato Pizza

I'm at a complete loss re: how to introduce this pizza. So I'll just say it was amazing - funny how that happens when you just go pick out exactly the ingredients you want - and move on.

1 pizza dough (made ahead by you or by someone else.... in my case a whole foods employee - they do make a really good pizza crust....)

1 small sweet potato
1 pear
1/2 cup pine nuts
1 large, sweet white onion
1 small bunch spinach

Pizza sauce
olive oil
balsamic vinegar
salt, sugar, honey

1 hard white cheese (pecorino romano)
some good goat cheese

1. Roast toppings. Chop the sweet potato and pear into small dice. Toss them with the pine nuts, olive oil, balsamic, sea salt and honey in a baking dish. Cover with foil and bake at 425 for 20 mins or so, till soft and browned where they touch the pan.

2. Caramelize onion. Chop roughly, heat some olive oil with salt, sugar and balsamic in a saucepan or deep frying pan, add the onion and stir to coat. Then let it sit there on med-low heat. After about 15-20 mins, when it's really gotten soft, add the cleaned & torn spinach on top to wilt it.

3. Prepare the dough & coat w/sauce.

4. When the onions & spinach are ready, layer those on. Then add the sweet potato mixture, then sprinkle with a light dose of both cheeses. Bake at 425 for about 20 mins.
