Spread an even layer of chutney on the inside of both slices
Pile your grated cheese evenly on one side and close it up.
Place the buttery sandwich into the preheated frying pan. Cover the pan with a lid to help melt the cheese. Keep an eye on the sandwich to make sure the bread isn’t burning. After 4-5 minutes, the first side should be golden brown and the cheese should be melting nicely.
Flip the sandwich and cook for another 4-5 minutes on the other side. You don’t need a lid for this part, because the cheese should be mostly melted by now. If at this point the sandwich is golden brown but the cheese isn’t melted, turn the heat down to low, and continue to cook the sandwich while flipping every minute or two so the bread doesn’t burn.
