Coat the bottom of the pan with a thin layer of olive oil, about 2 tablespoons, and place the pan over the coals of your campfire, on a grate. Mix the olive oil with a little butter or margarine if you’ve got it.
Add the onion and cook until just tender, about 2 minutes. Add the potatoes, peppers, and another 2 tablespoons of olive oil. Stir to coat. Stir occasionally for about 10 minutes, until potatoes start to brown.
Add a few tablespoons of water, and cover with foil to steam for about 5 minutes.
Add seasonings, continue to stir occasionally until fully browned, crispy, and tender in the middle. Serve alongside your favorite other breakfast items.
