Wash the potatoes well and bake in a preheated oven at 180 °C (356 °F) for 30 minutes or until done.
Chop the green onions, mix with the juice from a quarter of a lime and the olive oil and season with salt and pepper. For the spice lovers, you can add chili or chili flakes.
Remove the potatoes from the oven, mash them a little, add the cheese and then the green onion dressing. (You can also use other greens, depending on the season and what you have on hand.)
