Treat your tastebuds to this grilled peanut butter and banana sandwich!

I’ve got a lunch idea that will make everyone’s day: a grilled peanut butter and banana sandwich! I’ll show you how to pack it in a matter of minutes.

The Best PB & Banana Sandwich

Sometimes the greatest lunch ideas can be inspired by your kid’s favorite snack combos, and in this case, it’s peanut butter and banana. We’ve been pairing the two for years but only recently tried it in a grilled sandwich. The results were so delicious that I had to share them with you. This tasty lunch is the slightly tamer version of the Elvis Sandwich, which is a grilled sandwich with peanut butter, bacon and banana.

Now, if your child goes to a nut-free school they can still enjoy this sandwich made with any peanut butter alternative, but soy butter tastes the closest to peanut butter.

Creating delicious lunches with everyday ingredients is my jam, and I’ve compiled a TON of ideas into one source. You’ll find everything from sandwiches like this to bento boxes, pasta salads, and hot lunches, right here:

What is in a Grilled Peanut Butter & Banana Sandwich

Here’s what you’ll need to make this masterpiece:

  • Sandwich bread: use your favorite sliced bread.
  • Peanut butter: crunchy, creamy- it’s your pick! Or swap for nutella for an incredible grilled nutella sandwich.
  • Banana: you’ll need about half.
  • Butter: to give the bread a toasty glow.
  • Snacks: items like fruit, veggies, and snack bites.

Watch this grilled peanut butter goodness come together in this quick video!

Loving this idea? Once you’ve tried it, give this grilled PB & J a go- it’s a heavenly upgrade to everyone’s favorite sandwich.

How to Pack it for Lunch

Now, I’ll show you how to properly pack this grilled sandwich in the lunchbox with other snacks.

  1. Grill
    Assemble the sandwich and grill it until both sides of the bread are toasty and golden brown.
  2. Cool down
    Remove the sandwich from heat and allow it to cool down to room temperature- this step will prevent steam from building up in the lunch box and making the bread soggy.
  3. Add the snacks
    Place the sandwich in the lunch container and add any wet ingredients like fruit and veggies in separate compartments, so the bread doesn’t soak up their moisture.
  4. Pack it up
    Close the lunch box and pack it into a lunch bag with an ice pack, if desired.

Keeping grilled sandwiches crispy until school lunch

Now that you have a delicious grilled sandwich to pack for school, check out these tips for packing it properly:

Use a hard container
Having a sturdy, compartmentalized lunch container makes packing ideas like this one so much easier, and you’ll find the best lunch boxes for kids here.

Cool it fully
Don’t pack the grilled sandwich until it cools down to room temperature. Otherwise, the steam from the warm sandwich will make the bread soggy.

Bulk up this lunch
Teens and athlete kids need more fuel, so healthy snacks can help keep them going longer. Add baked banana chips, pizza egg cups, or blueberry yogurt parfait. Plus, I have some tips on how to pack yogurt!
