Gochujang mac-and-cheese toastie

Method

1. Bring a pan of salted water to the boil. Add the macaroni and cook for 8 minutes (until al dente – cooked but with a bit of bite), then drain. Meanwhile, melt the butter in a medium saucepan, then stir in the flour and cook for a minute. Slowly whisk in the warmed milk bit by bit to create a smooth sauce, which will thicken after a few minutes. Beat in the cheeses until melted, then stir in the gochujang, spring onions and sesame seeds. Add the pasta and stir together well.
2. Put a large frying pan over a medium heat. Butter one side of each slice of  bread, then place two of them butter-side down in the frying pan. Spoon plenty of the warm mac and cheese onto each slice, then top with the remaining bread with the buttered side on the outside. Flip after a minute or two and cook for another minute or until the bread is nice and toasted.
