Peel a medium-sized, sound onion, then chop it fine; place it in a sautoire on the hot stove with one ounce of butter, and let get a good golden color, adding half a pint of stewed tomatoes, or two good-sized, peeled raw tomatoes cut into small slices, a crushed clove of garlic, and season (should the tomatoes be fresh) with a pinch of salt and half a pinch of pepper, adding a teaspoonful of chopped parsley; let the whole cook together for ten minutes; then proceed as for the tomato omelet (No. 51).
