Preheat oven to 375ºF and line a medium baking sheet with parchment paper. Poke holes in sweet potatoes with a fork and rub with olive oil. Place onto the baking sheet and bake for 45 minutes. Cool potatoes at room temperature for at least 15 minutes.
Stir together buffalo sauce, melted butter, mayonnaise and garlic powder in a medium mixing bowl. Add chicken and stir well to coat. Slice potatoes in half lengthwise and scoop or flesh using a spoon. Leave some flesh around edges and bottom to prevent tearing. Scoop chicken mixture into each potato half and place it on the baking sheet. Bake 12-15 minutes to heat through.
Place 2 sweet potato halves in the large compartment of 4 MPOF teal container. Garnish with green onion. Add celery and carrot sticks to each small compartment and a small cup of blue cheese dressing.
