For each sandwich place two tablespoons each of the street corn mixture, and both cheeses dividing between 4 slices of bread. 

Top with the remaining slices of bread to form your sandwich. 

Preheat a grill pan or skillet over medium heat. Spray butter spray onto each sandwich, then place butter side down onto heated grill pan. Spray the other side of the sandwich with more butter spray., being careful spraying near exposed flame.

Grill sandwiches turning as they brown until the cheese is melted and the bread is toasty.

Cut in half and serve immediately.
