Sweet potato casserole should be topped with pecans, never marshmallows.Marshmallows are for s’mores, hot chocolate and little else.That’s an opinion that won’t be debated at my Thanksgiving table. We may debate over the value of Lululemon attire — overpriced and unnecessarily confusing athletic wear, in my opinion. I mean, I had to YouTube directions on how to wear this Christmas present, and two years later I still haven’t figured it out.
