In a mixing bowl, combine the active dry yeast, sugar, and warm water, stirring well. Let the mixture sit for about 10 minutes until it becomes frothy.

In a large mixing bowl, whisk together the all-purpose flour and salt. Make a well in the center and pour in the activated yeast mixture, yogurt, and oil. Mix until a shaggy dough forms, then knead for about 10 minutes until smooth and elastic.

Place the dough in a lightly oiled bowl and cover it. Allow it to rise in a warm area for about 1 hour, or until it has doubled in size.

Once risen, punch down the dough gently, divide it into 8 portions, and roll each piece into an oval shape about 8 inches long.

Heat a skillet over medium-high heat. Lightly grease it, then cook one shaped naan for about 1 minute until bubbles form. Flip and cook for another minute.

Mix melted butter with minced garlic. Immediately brush the cooked naan with the garlic butter and sprinkle with salt and chopped cilantro or parsley.
