Cut green chilies open and remove seeds. Cut lengthwise into halves; set aside. Combine tuna, mayonnaise and pickle relish in medium bowl.
Spread butter on one side of each bread slice; arrange butter-side down on large plate. Place cheese slices on bread. Top four bread slices with chilies and tuna mixture; close sandwiches with remaining bread slices butter-side up.
Cook sandwiches on a hot griddle or in batches in a nonstick skillet over medium heat until golden brown and cheese has melted, 3 to 4 minutes per side.
