Slow Cooker Sweet & Sour Meatballs

"This simple meatball recipe is so easy and delicious that I can’t believe I haven’t shared it until now. This is a side dish we have every year with our Christmas dinner. I love that you can set and forget it. You have enough going on when you’re trying to make a big holiday dinner that having a slow cooker dish (or something you can make ahead and freeze) is ideal! And they are an excellent potluck dish! I also serve these crock pot meatballs with sweet and sour sauce for a regular dinner over mashed potatoes or jasmine rice."
