Combine warm water, sugar, and yeast in a bowl. Let stand for 5 minutes until foamy. Add salt and flour. Mix thoroughly. Knead dough on a floured workspace about 20 times and form into a tight ball. Put dough in a well oiled bowl and cover with a damp towel. Put in a warm place to rise for 30-45 minutes. Dough won't rise much, but it doesn't need to. Turn dough out onto a floured workspace. Divide dough into 8 pieces and roll out with a rolling pin to about 1/8" thick. Grill naan pieces on a grill or electric griddle. In a pinch, a frying pan sprayed with some nonstick cooking spray will work. Grill for 1-2 minutes on each side. This recipe yields a very soft, chewey naan. Just the way I like it!
