Tacos with slow-cooked pork is an amazing meal you can make fresh in your truck. A small slow cooker is a great investment if you don't have one. It allows you to coom fresh without having to freeze a pre-cooked meal.
The life of a truck driver can be an unhealthy lifestyle, both physically and mentally. I know this isn't groundbreaking news. It's obvious that a job can lead to unhealthy habits when it requires long hours of sitting, lots of time away from home, tight deadlines, and little access to common amenities such as a kitchen or exercise equipment.
