Slow Cooker Honey-Mustard Lime Chicken

8 chicken legs
1/2 cup honey mustard (or 2 tbsp honey mixed with 1/3 cup Dijon Mustard)
1 lime, juice and zest (or 3 tbsp lime juice)
2 garlic cloves, minced
1 tbsp soy sauce

Combine all ingredients in the slow cooker, and stir to evenly coat the chicken. Cook on low 6-8 hours or until chicken is cooked all the way through. Serve with rice to spoon extra sauce on top.
