On your favorite slices of bread, spread peanut butter on one side of each slice.
If you are adding jam or jelly to this sandwich, spread peanut butter on one slice and jam or jelly on the other slice.
Slice up a banana and set aside.
If using fresh berries, clean and let dry before adding to the sandwich.
Frozen berries work just as well, this is what I used in my sandwiches. I used very small blueberries, but if you're using larger berries, thaw before adding.
Lightly drizzle the oil in the pan before heating.
Warm up the medium sized fry pan on low heat.
Place a slice of bread into the pan, peanut butter side up.
Add the sliced bananas on top of the peanut butter.
Next place berries on top or in between the bananas.
Lastly place the peanut butter side of the bread down on top.
Cook for about 2 to 3 minutes, gently flip, and continue cooking for another 2 to 3 minutes, or until lightly browned. The blueberries mostly stick to the peanut butter but some might fall out when you flip the sandwich, you can just stick them back in.
Remove the sandwich from the pan, place on a plate, cut in half.
Serve your Grilled Peanut Butter Blueberry Banana Sandwich immediately.
