Slice SPAM into the classic slices and then again lengthwise for matchsticks. Slice melty cheese into similar shape. Scramble one egg in a small bowl,
Using a whole sheet of lumpia wrapper, place a slice of SPAM and a slice of of cheese together. Stack another slice of cheese and SPAM on top.
Roll the lumpia and use the scrambled egg to seal it.
In a pot or pan large enough to accommodate the lumpia, heat frying oil to 350° F. Drop in lumpia and fry for about 10 minutes or until golden brown. Make sure to flip to fry both sides.
When lumpia is done frying, remove from oil and place on a cooling rack or paper towels to cool.
