Glazed Shallot, Walnut And Goat-Cheese Pizza

["Preheat the oven to 450u00b0 (or follow directions on package of store-bought dough).", "In a large heavy saute pan over medium-high heat, heat olive oil until it shimmers. Add onions and shallots and saute, tossing or stirring, until they turn golden.", "Push aside the onion-shallot mixture, drizzle a little extra olive oil, and add the crushed garlic, stirring, until it starts to soften. Add the sage leaves and toss all together, stirring until mixture is starting to brown slightly and is fragrant. Stir in the salt and pepper. Remove from flame and allow to cool to room temperature.", "Line a rimmed baking sheet with aluminum foil, grease with a bit of olive oil and sift some cornmeal over.", "If preparing dough from scratch, when the dough is ready roll out a portion suitable for one pie on a large, greased cutting board to fit the measurements of the pan. Transfer to the baking sheet and pull and pat gently to conform to the shape of the baking sheet.", "Brush the edges of the dough with a little olive oil so they will not be tough. Spoon the shallot mixture over the dough, leaving a 1"" margin all around. Top with the walnuts and the cheese; drizzle lightly with additional olive oil. Bake the pizza in the bottom third of the oven, about 10-20 minutes, rotating the pan halfway through the cooking, until edges are golden and cheese is browned in parts. Watch carefully to make sure the walnuts do not burn; you may wish to lower the temperature if the onion mixture, cheese & walnuts are browning too quickly.", "Remove from the oven, cut into squares, and serve."]
