Delicious and healthy Tex-Meal meal.
You can cut the potato by hand or if you have a chipper, a chipper will make fast work of it.
Leaving the skin on the potatoes adds fiber and makes this dish just a little more filling and satisfying.
Instead of duck fat you could use goose fat, or beef fat. An animal fat such as that is more satisfying to use than a similar amount of oil, as it doesn't all evaporate away and provides more satisfying foods for around the same number of calories. Instead of a teaspoon of melted duck fat, you could use 2 or 3 teaspoons of oil (more calories.)
