Disappearing Tripe

Have you ever been certain that you have a certain ingredient in your kitchen, only to find it is gone?   That happened to us today.  Hubby and I planned to make Menudo this weekend and knew we had the tripe in the freezer.  Tonight, hubby went to pull out the tripe to thaw.  We have no clue where it went.  We didn't cook it and we didn't toss it out.  Our final conclusion.....a tripe thief snuck into the house and took it.
