Start with selecting a protein for your bento box. This can be a hard-boiled egg, rolled-up deli meat, or leftover grilled proteins. Protein is an essential macronutrient that also helps keep kids full. It can stand alone or be an ingredient of a sandwich or wrap, for example.

Select a complex carbohydrate for lunch. This can be whole-grain bread to make a sandwich with the above protein, crackers, or leftover pasta. Carbohydrates are an essential source of energy, fiber, and help fill up hungry bellies.

Wash, peel, and prep a serving of fruit. Fruit is rich in vitamins and fiber and is perfect for a child's lunch.

Wash, peel, and prep a serving of veggies. Bite-sized veggies or pieces that are crunchy and dippable are a kids' favorite. Veggies add fiber, vitamins, and minerals to a lunch.

Dips such as homemade ranch, hummus, or sauces are a great addition to a bento-style lunchbox. They can add flavor and nutrition and are a great vessel for consuming more veggies.

Consider including a small treat in the lunchbox to keep kids looking forward to enjoying their bento-style lunches.

Separate wet and dry ingredients from each other. Crackers, for example, should go in their own compartment so they don't absorb moisture from other foods.

Place dips and sauces in small lidded containers. This will prevent other items from getting soggy and minimize any potential mess.

Bite-sized pieces for younger kids. Younger kids tend to love lunch for socializing and chatting with their friends. Cutting up food items into smaller pieces or quartering sandwiches can help make sure kids take bites between their conversations.

Make portions appropriate. Make sure you're packing enough food to keep hunger at bay as well as not too much since it can lead to food waste or anxious feelings for not finishing their lunch.
