This is the simplest salad one can make with lunch or dinner. A good accompaniment to dal-roti meal.
Onion (medium size) - 1 roughly chopped
Tomato (medium size) - 1 roughly chopped
Salt to taste
Red chili flakes - a big pinch
Sugar - 1 tsp
Mix all the ingredients and leave for 5 min, so that sugar dissolves completely and salad absorbs the spices.
