In a large bowl combine whole wheat flour, all purpose flour, sugar, salt and yeast
Add yogurt and 1/2 tbsp minced garlic. Add warm water and mix until well combined using a wooden spatula
Knead the dough in the bowl itself for about 5-6 min. until it becomes soft. Use the remaining 1/4 cup water during kneading to wet the hand and avoid sticking the dough to the hand. Cover the bowl and place it in a warm area and let the dough rise for about 1 hr
To make the toppings, mix 1 tbsp minced garlic, 1 tbsp olive oil and chopped coriander in a small bowl; mix well
Once the dough has risen to double its size, transfer it to a flat surface. Add some dry flour to avoid sticking the dough on to the surface. Spread the dough using hands and give it a rectangular shape (almost). Cut the dough into roughly 8 equal parts (see image above) and then give each of them a round shape. Roll the naan to roughly 1/4 in. in thickness
Heat a cast iron pan on medium-high heat. Put the rolled naan onto the preheated pan. Cook naan on one side for about 2 min on medium heat and then flip it over. Let it cook on this side for another 2 min. Meanwhile spread some water using a brush on the cooked surface to provide some moisture. Then, spread some toppings using a spoon. Once the other side is cooked, flip it over and just cook for 10 sec to remove the raw garlic flavor from the toppings.
