Whether you run in the morning or afternoon, lunch is an important meal because it's either helping you with your recovery or fueling your upcoming run. Yet some runners either skip lunch because they're busy at work or they eat some fast (often unhealthy) food on the go.

It's possible to have a lunch that's both quick AND nutritious. The key to a healthy lunch is balance. Try to incorporate at least three different food groups into your meal.

Make sure your lunch includes protein, complex carbohydrates, and fiber to provide energy and help you stave off hunger.

If you're bored with your current lunch routine, here are some suggestions for quick and nutritious lunches that don't require a lot of prep time. Most of them are easy to pack if you're brown-bagging it to work or school.
