This is probably the easiest dish in the world to make. All you need is a few ingredients and a slow cooker, and you are good to go. We like to think of it as the perfect snack or meal for game day, but you can easily do this any day of the week and serve it with some mashed potatoes on the side.
Mix Felix lingonberries and prepared mustard in slow cooker pan.
Add frozen meatballs and mix it with the lingonberry/mustard sauce.
Cook on low for 4 hours or high for 2 hours.
