Combine all the cheeses into a small bowl and stir together until you get a smooth consistency.
Combine the finely chopped chicken with hot sauce and stir.
Smear a little over a tablespoon of the mixture onto each slice of bread.
Divide half the chicken on top of each piece of the smeared bread.
Smear the other slices of bread with cheese and put the top on the sandwich.
Gently apply 1 pad of butter to the top of the grilled cheese and place it butter side down in your pan.
Turn the heat to high and butter the other side of the bread.
Check the brownness of each grilled cheese about every thirty seconds or so.
Take it off the pan when it looks brown on both sides.
Serve immediately.
