Slow Cooker Pork Tenderloin on a bed of onions on a white plate.

I just got back from summer vacation and let me tell you, it is days like this that I’m grateful for my slow cooker.  I already know I’ll hit up the grocery store first thing to replenish milk and fresh fruits and veggies and then I’ll spend the day procrastinating the mounds of laundry. A quick prep meal would come in handy, but slow cookers take forever right? Not so. See, I’ll grab a tenderloin at the grocery store. They cook in 3 to 4 hours. That means I can still utilize the convenience of the slow cooker while I catch up on tv shows do laundry. If the family is lucky, they’ll even get a side salad with it. Time to get back into the swing of things around here with regular life and enjoy the last few fleeting weeks of summer.
