Mini Polenta Pizzas (Gluten and Dairy Free)

These little mini pizzas are the result of some creative thinking to feed my two boys who don't eat gluten or dairy food (let that sink in for a second, no ice cream, cheese or regular bread). Anyway, we've learned some good meals that are not only pretty good for them, they taste good and aren't even that hard to make.

Tonight's dinner was Mini Polenta Pizzas.
Ingredients:
1 Polenta "chub" sliced into as thin discs as possible without the polenta crumbling
Marinara sauce
salami cut into eighths or sliced hot dogs pan fried to look like mini pepperoni
cooked white rice
dried oregano
salt and pepper to taste

I baked the polenta slices on a lightly greased half sheet in the over at 350 degrees for close a half hour. The package says 20 minutes but that wasn't working for me. Use your judgement though, if the slices are thin they'll cook faster and scorch faster too.
Heat up the marinara (I used the Tomato & Basil Marinara from Trader Joe's) and added the oregano after rubbing it into your hand and using a mortar and pestle to break it up. The rice can be room temp or warmer, cold doesn't work.
Assembly is pretty straight forward.
Polenta slice, top with marinara, a layer of rice (playing the part of the cheese here), top with salami or hot dog pepperoni pieces.
A little salt and serve.
My finicky son wolfed down two and then two more and my not so finicky son ate a total of five and a half mini pizzas.
