Wash the potatoes and boil them in a little water with a pinch of salt.
Wash the Swiss chard thoroughly, then drain.
Once washed, cut the center stem and leave only the leaves (some people boil the stems after removing the thicker fibers, but that is optional).
Finely chop the onion and cut the Swiss chard leaves into thin strips (you can roll them up so that the cut of the stems is perpendicular to the cut of the strips you are going to make).
Heat the oil and sauté the onion (some people include garlic at this step, but personally, I don't like it much since Swiss chard has a strong flavor), when the onion becomes transparent, add the Swiss chard and stir constantly for about 5 to 10 minutes over medium heat.
Cut the boiled potatoes into cubes of approximately one cubic centimeter (you can get about 30 cubes from one potato) and add them to the Swiss chard (you can peel the potatoes if you prefer).
Add the tomato purée (I have made it with canned purée when in a hurry, but homemade purée also tastes delicious) and stir to prevent it from sticking until the purée changes color slightly, then add the cup of water and salt and pepper to taste.
Reduce the heat and let it simmer for 10 to 15 minutes, stirring occasionally to prevent the potatoes from sticking. The dish will be ready when the Swiss chard changes color and feels soft to the touch.
