Pizza with Broccoli Raab, Roasted Onions and Olives

You got it, another Bitchin' Camero special!  Elegant, tasty, satisfying - oh, and healthy!

One pizza crust (I used multigrain pitas)
1 medium yellow onion
Olive oil
1 bunch broccoli raab (I used a combo of kale and gailan leaves, blanched)
1 pinch hot pepper flakes
1 clove garlic
1 lemon
1/2 cup grated mozzarella cheese
niçoise olives, pitted, sliced
2 sprig thyme (optional)
S & P to taste

Dice the onion and toss it in a small ovenproof sauté pan with a pinch of salt and enough olive oil to coat lightly, and the leaves of the thyme. Put the pan in the oven to roast, stirring occasionally, until the onion is cooked and golden, about 30 mins. While the onion is roasting, wash and chiffonade the greens - there should be enough to make about 2 cups. Peel & finely chop the garlic. Heat a large sauté pan and coat it with olive oil. Add the greens, season w/ s, p, & the hot pepper flakes, and fry over high heat until the greens are tender. Add the garlic and fry, tossing, for a few seconds.
When the onions are done, take them out of the oven and turn the heat up to 450° to 500°F. Lightly brush pizza crust the dough with olive oil, leave a 1/2-inch boarder dry. Evenly sprinkle the cheese on the oiled surface,spread the onions over, and top with the greens and the olives. Drizzle about 1 Tbsp olive oil over the pizza. Slide the pizza into oven & bake from 5-10 mins, until the crust is brown and crisp. Remove the pizza from the oven, sprinkle a few drops of lemon juice on it, slice and serve.
