Using a slow cooker is a great way to save time and money, especially in winter, when stews are awesome. Coming home to a hot meal that requires no preparation after a long day of work is so so nice.
Quick and easy! I whipped out these ingredients in the morning - leeks, celery, carrots, and stew meat. Chop chop chop!
Everything into the slow cooker with some salt and pepper and butter (of course). Set on low and leave for work!
After work - voila! Tasty meal for all of 10 minutes of prep work. I think I set my slow cooker to shut off to the "warm" state after about 8-10 hours.
