Mustardy Kale Salad with Sweet Potatoes

This recipe was a family favorite even before we made the transition to a fully plant-based diet.  Great Dijon mustard is the key paired with delicious fall apples.  This salad is generally my excuse to splurge a bit on honeycrisp apples at the store too.  If you are in need of cleaning out the fridge you can add any other roasted veggies you choose.
