Over medium high heat add coconut oil, butter and potatoes. Cook, stirring for about 5-10 minutes allowing potatoes to brown a little.
Turn heat down to medium low and continue to cook for another 7-10 minutes. Add in your onions and bell peppers. Season with a pinch of salt and pepper. Sprinkle on your old bay seasoning or whatever seasoning you prefer. Continue to flip or stir the potatoes for another 5-10 minutes.
Pour in 1/4 cup of the stock and put a lid on the pan. Let steam until most of liquid has evaporated. Taste for seasoning and add more spice/salt/pepper as needed.
Test your biggest piece of potato. If the potatoes are still a little underdone add another splash of broth and cover. Let cook until the liquid has evaporated.
