Spread butter on one side of each slice of bread, then flip the bread buttered side down and repeat with the other 4 slices.
Sprinkle the unbuttered sides of the bread with grated Gran Queso cheese, then a handful of cooked chorizo, a pinch of smoked paprika, then a sprinkling—or more—of sliced peppadew peppers. Top with more cheese and the top slice of bread butter side up.
Place the sandwich, buttered side down, in a non-stick fry pan over medium-high heat and top with the other slice of buttered bread. Cover with lid and let cook for 3-4 minutes or until golden.
Reduce heat to medium and flip sandwich to the other side and cook for 2-3 minutes or until bread is toasty golden and the cheese has melted. The second side will cook faster than the first so watch carefully. Repeat process with the other sandwich ingredients to make the other grilled cheese sandwich. Enjoy hot.
