After school, my girls are super-hungry, so I steer them toward a savory snack. These polenta mini-pizzas are a treat that I feel great about giving them. And, I can tailor them according to their tastes (and what I happen to have in the pantry)!
Preheat the broiler to high. Brush the polenta with the olive oil on both sides and place the disks on a broiler pan covered with foil. Broil until the tops begin to turn golden, about 1 minute (watch closely as broiler heat varies).
Flip the polenta disks over and spread about 1 tablespoon of the marinara sauce on each one, then top with cheese and other toppings (if using). Broil until the cheese is golden and bubbly, about 1 more minute. Let cool a few minutes and serve.
