Heat oil to about 370. Cut off the crusts of one piece of bread. Stack 3 pieces of American cheese and cut into long, quarter inch slices. Roll out the bread using a rolling pin to flatten. Take one stack of cheese and place on one end of the bread and roll. Dip into flour, then egg, the breadcrumbs. Let sit for one minute then place in the deep fryer. Turn with a spoon to get all sides. Keep in until golden brown. Place on a paper towel to drain.
