Preheat oven to 350 degrees and bake potatoes until soft enough for a toothpick to stick all the way in. I baked mine for about an hour.
In a medium skillet over medium heat, drizzle a little olive oil and add chopped onion. Let cook for 5 minutes and then add ground chicken and garlic. (I used chicken sausage.)
Cook until browned and remove from heat. Stir in salsa.
Roughly chop spinach and then add to skillet and stir in. The residual heat from the meat and onions will cook it down.
When potatoes are cooked, remove and let cook for a few minutes until cook enough to handle. Cut lengthwise and hollow out using a spoon. Add the parts of the potatoes that your remove from the skins to the skillet. Stir into meat mixture and salt and pepper as needed.
Fill potato skins with meat/potato mixture and top with a little cheese.
Return to the oven and bake for 10-15 minutes or until heather through and cheese has melted.
Top with cilantro, sour cream, bacon bits or whatever your family likes!
