Success! These little babies are delicious! I could even have used less cheese, and they would have been fine. The crust was a little puffy and nicely crustly, with no burnt edges. I had several for dinner, but these would be pretty fun as a party food too. You can't really tell from the picture because of the cheese, but two of them have mushrooms, one of them has mushrooms and tomatoes, and two are just plain cheese. I liked every combination.
1 cup grated cauliflower (I used a cheese grater, and it went pretty fast)
2 tablespoons roasted salted pepitas, ground (I ground them in my coffee grinder. If you don't have this around, double the cheese in the crust to 1/2 cup)
1/4 cup cheese for crust, plus ~1/4 more for topping
1/2 teaspoon Herbs de Provence (I used this because we were out of dried basil and the oregano was at the back of the cabinet, but you should use whatever pizza seasoning you like)
~1/4 cup pizza sauce (I used jarred sauce from the pantry)
Pizza toppings (I had fresh mushrooms and some grape tomatoes on hand, and Joel Fuhrman likes them too)
Preheat oven to 450. Line a muffin tin with 6 foil muffin cups and spray them with non-stick cooking spray.
Grate enough cauliflower to have a cup of it (around half a head). Put it in a microwave-safe bowl and microwave it for 4 minutes. (Almost everyone else on the interwebs says to nuke it for 8, but that's WAY TOO LONG in our microwave. I also saw a recipe that didn't microwave the cauliflower at all, so I split the difference and went with 4 minutes.) Let it cool for a couple of minutes so that when you add the cheese and egg it doesn't get weird. Stir in the ground pepitas, cheese, herbs, and egg and combine thoroughly. Divide evenly among the 6 muffin cups until it's evenly divided.
Bake for 10 minutes, until the crusts are a little puffy and starting to brown on the edges (but not too brown!). Remove from the oven, turn the oven up to broil, and while it's heating, top your crusts with a spoonful of sauce, toppings and cheese. Put under the broiler until the cheese is bubbly.
Remove. Let cool for a couple minutes to let the cheese set up, then pop the tarts out of the foil cups. Enjoy!
