Boil or microwave potatoes until fork tender. Drain and set aside.
Heat oil in a heavy bottom pan or a cast iron skillet. Add onions, peppers and cook on medium flame for 5~6 minutes.
Stir in the garlic and cook for 1 more minute.
Next add the boiled potatoes and cook stirring, occasionally until the potatoes are slightly roasted, about 4~6 minutes.
Season with salt and pepper. Sprinkle fresh parsley and serve.
