How do I store leftover Cinnamon-Spiced Chicken Thighs with Roasted Sweet Potatoes?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep medium sweet potatoes from drying out.

Can I substitute ingredients in Cinnamon-Spiced Chicken Thighs with Roasted Sweet Potatoes?
