2. Poke holes in sweet potato. Place on cookie sheet ( use non stick aluminum foil), and bake in oven until knife can be inserted without resistance), about 10-15 min.
3. When done , cut in 1/2 , scoop out innards taking special attention not to break the skin ( u will need them for the filling soon).
4. Place hollowed out potatoes back on sheet pan . Sprinkle with EVOO and place back in over for 10 min.
5. While skins are crisping, take filling and add milk, sat and pepper to taste . Add only enough milk to keep everything blended , don't add to much or it will be runny ).
