In a large bowl, whisk together the garlic, soy sauce, hoisin sauce, chili sauce, mirin and sesame oil. Add the pork belly and toss to coat. Cover and refrigerate for at least 2 hours or overnight.
Once the pork belly has marinated, remove from fridge. Heat 2 tablespoons of olive oil in a saute pan set over medium-high heat. Add the pork belly, and cook until crispy, turning every minute or so. This will take about 10 minutes. Remove from heat and transfer to a plate that has been lined with paper towel to get rid of any excess grease.
Preheat your oven to 475 degrees F and if you are using a pizza stone, place it in the oven at this point.
On a pizza peel (or a large baking sheet if you are using one), sprinkle a layer of corn meal. Cut your dough into 2 (for larger pizzas) or 3 (for smaller pizzas) equal-sized portions. Form 1 portion of the dough into a circular shape, stretching and shaping where necessary. You may need to bake each pizza separately, so start with one and then go from there.
When your dough is to your desired shape and size, spread about 1/2-1 (depending on how many pizzas you are making) cup of the barbecue sauce on top. Arrange half of the pork belly on top and then sprinkle with 1-1 1/2 cups of the cheese.
Place the pizza in the oven and bake for 7-10 minutes or until the cheese is bubbly and brown and the edges of the dough are also brown. Remove from oven and let stand for approximately 4 minutes before serving.
Repeat for the second and third portions of dough.
Sprinkle with fresh cilantro and micro greens and serve!
