Quarter the potatoes or cut into large cubes, place in cold water.
Bring to a boil, when potatoes are half cooked (3-4 minutes), add the cut-up chard. Boil until cooked (4-5 minutes).
Strain into a colander and let rest for a few minutes to ensure most of the water drains out.
Add salt, pepper, and LOTS of olive oil. Add a bit of pressed garlic if desired.
Mix well and serve.
Chefs note: All quantities can be adjusted to taste (more potato or more swiss chard), and the potatoes can be cooked more or less depending on how firm or mushy you like.
