Divide the pizza dough in half. On a lightly floured surface roll out one of the halves of dough into about a 10-inch circle. The dough should be fairly thin. Spread half of the cornmeal around on the pizza peel and place the dough on top. If you do not have a pizza peel then prepare the dough on a lightly greased baking sheet.
Rub 2 teaspoons of olive oil and garlic over the pizza dough including the edges. Grill the pizza for 3 minutes to par bake the crust. Use the pizza peel or large tongs to remove it from the grill.
Arrange the burrata cheese, zucchini, peas, asparagus tips and ramps around the pizza. Leave about 1” around the edge of the pizza for the crust.
Grill until the pizza is crisp and golden brown and the cheese is bubbling, about an additional 5 to 6 minutes. Sprinkle with truffle salt and black pepper.
Cut into equal slices and serve immediately. Repeat with the remaining pizza dough.
