PREHEAT the oven to 450°F, preferably including a pizza stone.
MELT the butter and olive oil in a wide skillet over medium heat.
ADD the onion and salt. Cook on medium-low heat, stirring occasionally until onions are very soft and light golden brown, 15-20 minutes. Stir in the figs, lemon juice and honey.
Meanwhile, DIVIDE pizza dough in half. Roll out on a floured surface to make two 10-inch squares or rounds, about 1/4-inch thick.
BAKE one at a time on a baking sheet or preheated stone until golden brown on bottom, about 6 minutes. Remove from oven.
TOP the browned side of each crust with half the onion-fig mixture.
SPRINKLE with gorgonzola cheese. Return to oven and bake until cheese is melted and crust is crisp, 6-8 minutes.
