Prepare a grill fire with a pizza stone to 350° if using a Big Green Egg or 400° using a propane or kettle style grill. Add hickory chunks for smoke flavor.
Brown ground beef in a skillet, breaking it up as it cooks until browned and starts to crisp. Drain excess grease if needed. Add Worcestershire sauce, salt and pepper, stir until combined. Cook 2 minutes. Remove from heat and set aside.
Roll out the pizza dough, one at a time, to desired thickness. Line a flat baking sheet or pizza peel with parchment paper. Roll the edges over around the crust.
Brush with 1 tablespoon olive oil.
Spread 1/3 cup of pizza sauce over the dough in a thin layer.
Sprinkle with 3/4 cup mozzarella cheese.
Add 1/3 of browned ground beef, 1/2 cup colby jack cheese, tomatoes, onions and 1/4 cup mozzarella.
Sprinkle the pizza stone with 1 tablespoon cornmeal.
Slide pizza and parchment paper on the pizza stone and cook with the grill closed.
Remove parchment after about 2 minutes. Use a large spatula or metal pizza peel to turn every 5 minutes, cooking until crust is golden brown and cheeses are melted.
Remove to a cutting board and rest 5 minutes before slicing.
Repeat with remaining ingredients.
