Lunchbox Builder for Kids
Tap what you are packing and this checks it against the formula the USDA's school meal standards are built on: one protein, one whole grain, and at least one fruit or vegetable. It also tells you which of the nine major allergens the box carries and whether it needs an ice pack. Same building blocks as our school lunch guide.
A school tray also has to include milk, but a packed lunch does not fail without one, so a missing drink is flagged here rather than counted against the balance.
What is going in the box?
Pick a few things to check the box. The five ready-made days below already work if you would rather not.
Five balanced lunchboxes, one per school day
Every box below passes the same check the builder runs, packs a drink, and is safe for a nut-free classroom. Rotating a small set beats reinventing lunch every morning.

Common school lunch allergens
Nut restrictions vary by school and often by classroom, and they change year to year. Check your school's policy rather than last year's.
| Allergen | Where it hides | Easy swap |
|---|---|---|
| Peanut / tree nut | Granola bars, some baked goods, trail mix | Sunflower seed butter, seed-based snacks |
| Egg | Mayonnaise, baked goods | Mustard or hummus as a sandwich spread |
| Wheat | Bread, crackers, soy sauce | Gluten-free bread, rice-based sides |
| Milk | Cheese, yogurt-based dips | Dairy-free cheese alternatives if needed |
Where this comes from
The protein-plus-grain-plus-produce formula, the nut-free swaps, and the below-40°F food-safety rule are all from healthy school lunch ideas for kids, which cites the USDA's school meal standards, its packed-lunch food-safety guidance, and the AAP on managing food allergies at school. If lunch keeps coming home untouched no matter what you pack, why won't my kid eat school lunch covers the reasons that usually are not the food. The named boxes link through to full recipes, and the daily needs chart has the sleep, water, movement and added-sugar targets that sit behind all of this.
The allergen flags cover the nine major allergens and are drawn from our own recipe ingredients, tagged conservatively. They are a starting point, not a clearance: always read the label on anything packaged, since cross-contact and hidden allergens in sauces and seasonings are easy to miss. If your child has a diagnosed food allergy, your allergist's plan beats any checklist, including this one.
