Pork Sandwhiches

I bought a "picnic" pork roast at the store weeks ago when they were on sale.  I got it for $1.58/lb. and stocked the freezer full of them. I put it it in the crock pot before work today, still frozen.  I came home and it was perfectly shredded.  I drained the juice and added an entire bottle of BBQ sauce to it and let it simmer about 30 min longer.  I served it on kaiser rolls with fruit salad. Crowd pleaser!
