I smoke a 6-10 pound Boston Butt ahead of time, slicing off some for a dinner and then pulling the rest for pulled pork sandwiches and of course Barbecue Lasagna. If you're accustomed to pulled pork you are ahead of the game as there are many pulled pork recipes online. Too much work? There are ready-made pork alternatives in most grocery stores. Same for barbeque sauce -- there are good recipes on the web or use your favorite store-bought brand. I guess I use about 2 pounds of pork in the lasagna. Mix sauce with pulled pork in a sauce pan and bring it to a slow simmer so it will spread easily.
