Combine flours, yeast, yogurt, oil, nigella seeds, sugar and salt in a mixing bowl. Add enough water to make a smooth and soft pliable dough. Cover and set aside for about 1 hour or until the dough is doubled in volume.
Make the Garlic Topping:
Heat oil/ ghee in a small saucepan. Add the garlic and chopped cilantro; cook till garlic turns golden.
Make Garlic Naan:
Preheat the broiler to High.
Divide the dough into 8 equal pieces. Roll each piece into a round or tear shaped naans.
Brush the top with the garlic oil and place on a baking sheet.
Broil for about 2 minutes, then flip and broil for another 1 minute. Watch the oven like a hawk to make sure that the naans don’t burn.
