Cut 3 yukon gold potatoes into rounds that are a 1/4 inch thick, then cut each slice into 4 evenly sized quarters, add the potatoes into a stock pot, fill with cold water, just enough to cover the potatoes, heat with a high heat
Meanwhile, cut 1 green bell pepper into thin strips, 1 red bell pepper into thin strips, thinly slice 2 small (or 1 large) onions, and cut a slit on 6 cloves of garlic (skins on)
Exactly 10 minutes after turning the heat on the potatoes they should be cooked al dente, you dont want to over cook them, or they will break apart when you fry them, pierce one with a toothpick, if it easily goes in but with resistance, they are perfect, drain into a strainer and run some cold water over the potatoes
Heat a large deep pan with a medium-high heat and add in 1/3 cup extra virgin olive oil, after 1 minute add in the sliced onion and the cloves of garlic, mix with the olive oil, after 2 to 3 minutes and the onions are translucent, add in the strips of green and red bell pepper, continue to mix with the olive oil, after 6 minutes and the bell peppers are tender, add in the boiled potatoes, gently mix together so the olive oil is coating all the potatoes, mix every 1 to 2 minutes
About 12 to 15 minutes after adding the potatoes and they have developed a light golden color, season everything with sea salt & black pepper, mix together and transfer everything into a large serving dish, sprinkle with freshly chopped parsley, enjoy!
