Place all dry ingredients in a bowl then create a well in the middle and add the oil and yogurt then mix until a ball of dough forms.
Turn dough out on the counter and knead until very smooth, about 5 minutes, then let rest for 10 minutes.
Divide into 8 equal pieces, roll one piece of dough until very thin then fill one side with a portion of the cheese, fold over, seal and roll to close.
Heat a skillet with a small amount of butter and then one at a time, cook each naan for about 90 seconds on each side until it begins to color. Repeat until all dough is used.
