First of all slice your tomatoes and put them aside

When done, apply butter on both sides of the breads and once done flip the sides from which the buttered side is facing down this is called "buttered side down"

Then add on your cheeses, tomatoes, basil, jalapenos, salt and pepper at the end. Close your sandwich with the other bread slice with buttered side up and grill it on grill pan until cheese melts(turning the sides continuously)

Finally take the sanwiches of grill pan, place on plate, cut triangles and serve!!!
