We first had these at Sticky Fingers (the best BBQ restaurant!!). Anyway, we've recreated them at home lots, using leftover baked potatoes and cooked chicken. It's a very informal creation....
Leftover baked potatoes (I frequently bake a couple of extras when I'm roasting a chicken)
Leftover cooked chicken
sour cream or plain yogurt
bacon bits, optional
Halve potatoes and scoop a fair amount out of the skins, leaving a 1/2-inch thick layer or less. (I feed the potato insides to the kids since they don't like their food mixed or like potato skins). Scoop in some chopped cooked chicken. Top with BBQ sauce. Heat in the oven (something like 350 degrees) until warmed. Sprinkle with cheese and pop back in the oven until cheese is melted. Top with sour cream or plain yogurt and sprinkle with bacon bits. Mmmm...
