Begin by melting the non-dairy butter in a large heavy bottomed frying pan.
Place the sourdough into the pan and let it begin to soak up the butter and toast (2mins).
Add two slices of cheese to both pieces of sourdough and let them melt (4mins).
Once the cheese has started to melt add spoon the kimchi on to just one slice of sourdough and top it with the second slice to make your toastie sandwich.
Keep cooking the toastie until the kimchi has warmed through (2mins).
Cut the sandwich in half and enjoy while still hot.
