How to Pack a Grilled Chicken Pesto Sandwich for Lunch
Now, let me show you how to prepare and pack a proper grilled cheese in the lunchbox so the bread stays nice and toasty.
- Assemble
Spread the mayonnaise and pesto onto both slices of bread. Top one slice with the chicken and cheese. Assemble the sandwich and butter on both sides. - Grill up and cool down
Heat a non-stick pan over medium-high heat, and grill the sandwich like you would any grilled cheese. Remove it from the heat, and allow the sandwich to cool down to room temperature before packing it into a lunch container. - How to add snacks
If you wish to include fruit and veggies, make sure to pack them separately from the sandwich, so the bread stays crisp and fresh. A compartmentalized lunch container comes in handy for lunch-packing moments like this. - Pack it away
Close the container and place it in the lunch bag with an ice pack.
How to keep grilled sandwiches crispy until lunch
Pack sandwiches for school lunch that remain crispy and delicious is possible when you follow these tips:
Don’t let the sandwich get squished!
Ditch the ziplock bag and pack your grilled sandwich in a hard, sandwich-sized container to ensure everything stays fresh and does not get flattened in the lunch bag.
Allow it to cool down
Why should we let the sandwich cool after cooking? Great question! This trick prevents steam from building up in the container and making the bread soggy.
Add more nutrition
Want to make this lunch healthier? Add veggies, fruits, or other nutritious lunch sides like banana chips, fruit salad, no-bake oatmeal energy balls, or chocolate avocado pudding. Epic!
Pack sides separately
Keep your grilled sandwich crispily delicious by packing fruits and veggies in a separate compartment of the lunchbox. This prevents your sandwich from getting soggy!
