Consider buying wheat bread from your local grocery store if you don’t already have it at home. Take two pieces of wheat bread and toast them in a good quality toaster. Set the toaster to achieve the desired settings. Once the bread is toasted, consider removing it from the toaster gently to prevent it from breaking.
It is recommended to allow the bread to cool down to room temperature. This can be done by letting the bread sit on your kitchen table for at least 5 minutes. Never put the bread in a refrigerator as this can help certain bacteria and microorganism grow on it.
Cooling down the bread is extremely important. If you put the peanut butter on hot bread it is likely to melt and cause a drippy mess when you eat the sandwich.
Cut a banana into small pieces using a knife. This can be done while the bread is toasted in a toaster. Now apply a layer of peanut butter on one side of each toast. Put the pieces of a banana on the same side as peanut butter. Flip over the sandwich so the peanut butter side inwards. Cut it in half and enjoy.
