Put the potatoes in a pot of cold water, salt, bring to a boil and cook for about 25 minutes. Drain them, let them cool, peel them and then dice them.
In a non-stick sauté pan, heat the oil over high heat; sauté the onion for 4 min, then add the peppers and sauté for 4 min as well.
Pour the potatoes, chicken, garlic, paprika, and thyme into the sauté pan.
Add salt and pepper. Mix then press all the ingredients into the bottom of the sauté pan with the back of the spoon. Cook without stirring for about 5 min until all the ingredients are golden brown.
