This isn't really a recipe per se, but it is delicious! And if you use baking potatoes (the larger ones) you can get by with 1/3 to 1/2 of a potato per person.
Taco-Topped Baked Potato
4 baked potatoes (or 2 large baking potatoes)
1 lb taco meat
shredded cheddar cheese
green onion, thinly sliced
tortilla chips, crushed
Like I said, it's not really a recipe but another way to dress your baked potato to make it a meal on it's own. I served fresh sweet corn with our Taco-Topped Baked Potatoes. Yum!!
