Butter the 4 slices of the bread with the Kerrygold butter.
Place two of the slices in a saute pan. Layer the bread with the Skellig, then the bacon, then the jalapenos, and top it off with the Dubliner. Divide the filling ingredients between the two sandwiches.
Place the other two slices of bread on top of the sandwich. Heat over medium low heat for about 5 minutes per side or until the cheese has melted and the bread is toasted.
