Mix the naan ingredients, except the garlic and cilantro, in a large bowl. Mix until combined. Pour onto a surface and knead for about 10 minutes until smooth. Cover and allow to rise for 2 hours.
Roll out the dough on the counter and add the cilantro and garlic. Roll the dough up around the cilantro and garlic, then roll the long over itself. Repat the process to incorporate the garlic and cilantro into the dough. Cover with a damp paper towel and allow to rest for 20 minutes.
Roll the dough into a log and cut into 4 to 6 balls depending on how large you want the sandwiches and how much leftover naan you want. I cut mine into 4 and the amount of filling I made filled 3 of them for huge sandwiches and I had one bread leftover.
Roll each ball into a uniform shape folding the dough in on itself to create a smooth outside layer. Place seam side down. Cover the completed dough balls with a damp paper towel. Allow to rise for 2 hours.
Preheat the pizza oven to about 750, or your regular oven with a baking steel as high as it will go with convection turned on if possible.
Roll the dough as thin as you can and put the thin round directly onto the baking steel or onto the cooking surface of the pizza oven. Cook in the pizza oven about 3-5 minutes until browned on top and bubbled up. In an oven, you may want to do about 6 minutes, then flip for a few more minutes. You could also do it on a grill.
Remove from heat and wrap in a clean kitchen towel. Repeat until all are done and together in the kitchen towel.
