Spread the softened butter over one side of the tortilla. On top of that layer, the shredded chicken is followed by the grated cheese.
Fold up two opposite sides of the wrap towards each other, then flip it over before rolling it up tightly.
Toast until golden brown in a skillet or oven for about two to three minutes and shut the heat off.
Cover the tortilla with cling foil for a few minutes before serving (for the cheese to melt perfectly).
Notes
Of course, you may add some chicken seasoning if your children are picky eaters. You also have to leave the tortilla on the pan longer if you kept it in the fridge.
