Grilled-Asparagus, Tomato, and Fontina Pizzette

Preheat grill for direct- and indirect-heat cooking to 500 degrees (if grill does not have a temperature gauge, set an oven thermometer on upper rack). If distance between grill grates is 1 inch or greater, preheat a metal cooling rack directly on grill to prevent dough from sinking through.

Toss asparagus and scallions with oil; season with salt and pepper. Grill, turning a few times, until charred in places but still firm, 2 to 3 minutes. Let cool slightly; when cool enough to handle, cut scallions into 1 1/2-inch pieces.

Turn dough out onto a pizza peel or thin wooden cutting board dusted with semolina (do not punch down). Divide into thirds. Starting in center of each and using both hands, press down and outward with your fingertips while allowing dough to slowly turn. Gradually work toward edges, leaving a 1-inch border of undisturbed dough, until each is stretched to an approximately 7-inch round.

Lightly drizzle each round with oil; season with salt and pepper. Transfer to grill over direct heat and cook just until set and lightly charred on bottoms, 2 to 3 minutes. Remove from grill.

Divide half of cheese evenly among crusts, then top with asparagus, scallions, tomatoes, and thyme. Sprinkle evenly with remaining cheese. Return pizzette to grill over indirect heat. Cover and cook until crusts are golden brown in places, asparagus is crisp-tender, and cheese is bubbly, 6 to 8 minutes. Serve immediately.
