2 balls pizza dough (~10 ounces each, preferably whole wheat)
2 Tbsp olive oil, plus more for drizzling
2 cloves garlic, minced
1 large bunch kale, or two smaller bunches (I like Red Russian), washed and dried and roughly chopped
wedge of lemon
flour or semolina for dusting
~1/3 cup roughly chopped walnut halves (do not toast, as they'll brown in the oven)
~1/4 cup crumbled blue cheese
1/2 red or yellow onion, sliced into thin half-moons
Preheat your oven, with a pizza stone if you have, to 500 degrees for an hour. If your pizza dough has been refrigerated, let it sit, covered, at room temperature for about the same amount of time.
While the oven is preheating and the dough is warming, prepare the kale. Heat the olive oil in a large pot over a medium heat. Add the garlic and saute until starting to brown. Add the kale along with a pinch of salt, and saute until softened, covering the pot between stirring to help the kale wilt. When it's almost done, squeeze the wedge of lemon over the top and stir to combine. Turn off the heat and set aside.
Place one ball of the pizza dough on a lightly-floured counter top, and press outward into a thick disk (leaving a 1" unpressed area along the edge as the crust). Pick up the disk and let it drape over the backs of your hands, letting gravity help you stretch it into a 12-14" circle. If the dough resists, let it relax for a few minutes, then try again. Place the stretched dough on a peel (or overturned cookie sheet or cutting board) that's lightly dusted with semolina or other type of flour.
Take half the sauteed kale, and sprinkle evenly over the dough. Scatter half the walnuts, half the blue cheese, and half the onions on top. Drizzle lightly with olive oil, and sprinkle with a pinch of salt. Slide the pizza onto the preheated stone in your oven, reduce the heat to 450, and bake ~7-10 minutes, until the crust browns. Remove the pizza from the oven, let cool for a moment, and slice and serve.
