Preheat the Traeger grill to 375F
Fill a large bowl with water.
Wash all of the russet potatoes.
Working with one potato at a time, cut it in half lengthwise. Use a grapefruit spoon if you have one to scoop out the inside. Leave a ½" border of potato along the outer peel.
After scooping out the flesh, soak the potato in the bowl of water. This will prevent the potato from turning brown.
Continue the process until all of the potatoes are prepped.
Remove the potato skins from the water and spread out on a sheet pan.
Drizzle all the potatoes in a light coating of vegetable oil and rub around for an even coating.
Lightly season with salt on all sides.
Once the Traeger has preheated to 375F and the potatoes are seasoned with salt, place them on the grill peel side up.
Cook them for 30 minutes or until the potatoes are fork tender.
Once they have cooked completely, use tongs to flip the potatoes over.
Fill each potato with a generous pile of shredded cheese and cooked bacon bits. Close the lid and cook the potato skins for another 3-5 minutes.
Once the cheese has melted, remove the potato skins to a serving platter or sheet pan.
Top each potato skin with sour cream and chopped chives.
