Remove crusts from slices of bread. Please note, this is totally optional. If your kids love the crusts, just skip this part.
Flatten out each bread slice with a rolling pin or the palms of your hands.
Place one American cheese slice on each flattened bread slice.
There's two ways you can roll this up. You can roll it up from one of the corners or roll it up from the long side. Continue with the remaining bread and cheese.
Next, mixed together the softened butter and mayonnaise. The mayonnaise is not only going to give it amazing flavor but it helps to give it a pretty golden brown color too.
Coat each grilled cheese dipper with this butter mayo mixture. Heat up a non-stick pan over low-medium heat. A nonstick pan is super important here. If any cheese oozes out, it will be easy to wipe up. Also, you never want the pan super hot when making grilled cheese because you don't want the outside to get brown before the cheese has even had a chance to melt.
Then, place grilled cheese dippers in a lidded container. No need to reheat these as they will get warm again once they are dipped into the hot soup.
