My advice for cooking while traveling is to first make sure you are staying somewhere with access to a kitchen or, if you're driving to where you'll be staying, bring a portable induction cooktop or electric skillet. Plan your meals ahead and cook in large batches, making meals that will last the week to be repurposed in leftovers. For example, pasta sauces are a great choice for vacation meals as pasta is easily available and easy to make on the fly!
