Staying with the theme of Quick this meal may seem out of place. But trust me it isn't. Getting this meal in the crockpot takes only a few minutes and then making mashed potatoes and gravy only takes a few minutes. This meal is so worth that tiny bit of effort. After tonight's dinner, mash up the remaining celery, carrots and onions that are in the roast. It will make your pork tacos (carnitas) so delicious on Thursday. You are going to love this flavor!
