"Ono" in Hawaiian means good. A "So Ono" sandwich is a very tasty, very good sandwich. My So Ono Grilled Pineapple, Spam & Cheese is the best tasting sandwich in the competition.
Cut the Spam into 1/8 inch slices and grill them for about 8 minutes until browned
Grill the pineapple rings until grill marked and warm about 5 minutes
Assemble the sandwich. 2 Slices of Spam then 1 pineapple slice then the cheese slice.
Place the sandwich in a skillet that is slighty warm for 2 minutes then flip for 2 more minutes. The pan should be on low heat.
Remove from the heat add 1tbsp of mustard and serve with 2 slices of grilled pineapple.
