Preheat your oven to 400°F. Preheat your grill to medium heat (350-400°F).
Heat the water until warm (about 1 minute in the microwave). Stir in the honey, then add the yeast. Cover and let sit for 5 minutes until foamy.
In the bowl of a stand mixer, combine the gluten-free flour, baking powder, garlic salt, 2 tablespoons olive oil, apple cider vinegar, and yeast mixture. Mix until a dough forms.
Place the dough onto a piece of parchment paper dusted with gluten-free flour. Knead lightly until smooth, then roll into a 10 x 14-inch rectangle or desired pizza shape.
Transfer the dough on the parchment paper to a baking sheet. Bake for 10 minutes.
Remove the crust from the oven and brush the top with the remaining 2 tablespoons olive oil.
Carefully flip the crust over using a pizza peel or another sheet of parchment paper so the olive oil side is facing down.
Top the uncooked side with your favorite pizza sauce, cheese, and toppings.
Carefully transfer the pizza to the preheated grill with the olive oil side down.
Close the grill lid and cook for 7-10 minutes, or until the cheese is melted and the crust is golden brown.
Remove from the grill and let the pizza cool for 2-3 minutes before slicing and serving.
