Schools are back in session and that means parents are in the kitchen preparing daily lunches for their kids. So how can you prepare the healthiest lunches for your children in just minutes?

As a doctor who happens to have a degree in nutrition, here’s my prescription:

• Involve your kids in the process.

• Explain to them that they should like what they eat but not always eat what they like. We all have to make choices and even little ones can start to learn that.

• Lead by example. Your kids are more likely to eat well if you do, too.

• Make it fun and recognize their efforts.

• Healthy eating can be delicious eating. Look online for easy, inexpensive recipes and make them together.
