To quickly thaw one pound of frozen pizza dough, brush it with olive oil, cover it with plastic wrap and microwave it at 100 percent power in 20-second bursts just until softened, but not heated. Cut the dough into 4 pieces and microwave it in 10-second bursts until it reaches room temperature.

2 pounds frozen pizza dough, thawed and cut into 8 pieces
3/4 cup part-skim ricotta
1/4 cup freshly grated Parmesan cheese (1 ounce)
Salt and freshly ground pepper
Vegetable oil, for the grill
4 large heads of radicchio, each cut into 8 wedges
3 large garlic cloves, minced
1/2 pound part-skim mozzarella, cut into 8 slices
How to Make It
Lightly brush several large baking sheets with olive oil. On a lightly floured work surface, roll out 1 piece of dough to an 8-inch round about 1/4 inch thick. Repeat with the remaining dough. Transfer the dough rounds to the prepared baking sheets.
In a small bowl, combine the ricotta with the Parmesan cheese. Season the cheese mixture generously with salt and pepper.
Light a grill. Lightly oil the grate. Arrange the radicchio wedges on a large baking sheet and drizzle with 3 tablespoons of the olive oil. Sprinkle the minced garlic over the radicchio wedges and season with salt and pepper. Grill the radicchio wedges over a hot fire, turning them occasionally, until they are wilted and charred in spots, about 3 minutes. Return the radicchio wedges to the baking sheet. Clean the grill grate with a wire brush or a crumpled piece of aluminum foil and tongs.
Have all the ingredients near the grill. Brush the dough rounds with some of the remaining olive oil. Grill 2 or 3 rounds at a time just until the bottoms are set and lightly charred, about 1 minute. Quickly, flip the rounds and top each one with a slice of mozzarella, one-eighth of the radicchio and one-eighth of the ricotta mixture in the center; season with salt. Immediately fold the dough over the filling to loosely form calzones. Using a spatula, transfer the barely cooked calzones to a large baking sheet. Repeat with the remaining dough rounds and filling.
Brush the calzones with the remaining olive oil. Grill the calzones over a low fire, turning frequently, until golden and charred in spots and the cheese is melted, 3 to 4 minutes longer. Transfer to a large platter and serve.
