Put some flour in a bowl, enough that it looks like just a bit less than how much bread you want. Throw in some salt and any other spices you want, mix it up. I've said before but I pretty much always use white whole wheat flour. That way you've got the nutritional benefits of whole grains without the somewhat overpowering flavor.
Add a bit of yogurt and/or sour cream (remember, it's always easier to add more to something than to take it out. Err on the side of not enough yogurt so you can add more if needed). In theory, it should be about equal weights of flour and yogurt, but don't take it too seriously.
Mix together; I like to use a rubber spatula and smear the mix down and around the bowl, folding it over itself to combine. You want your dough to be pretty thick, not very wet at all.
Melt a tiny bit of butter and some oil in a pan. Either shape the naan and place it in the oil on medium heat, or do what I do and put the dough in the pan as a lump, then spread it out to shape in the pan. You don't want it to be too thick or the inside won't cook, I'd say no thicker than your thumb.
Cook until it's nicely browned, and devour. Super simple, super quick, delicious.
So that's:
1: mix flour, salt, and desired spices.
2: add approximately equal weight yogurt or sour cream, combine thoroughly.
3: pan fry on medium to medium high heat.
