Barbecue beef sandwiches are one of those things that require very little preparation and taste oh so good! And when I say very little preparations I mean it. There’s no fuss, no mess and no standing over a hot stove or oven watching. If you have a crockpot you can make delicious barbecue beef sandwiches and your family will think you spent the day in the kitchen. Ssshhh, don’t tell them you didn’t.
