Pre-heat the oven to 450°F. Remove core from the half cabbage and cut into four similarly sized chunks.
In a mixing bowl, combine sauce ingredients. Liberally paint both sides of each cabbage slice, making sure to cover creases.
Bake in the oven for 10 minutes, then remove cabbage and re-paint with sauce on both sides.
Cook for a further 10 minutes, or until cabbage started to brown on the outside.
Serve immediately as cabbage chunks, or chop into smaller pieces with sweet soy sauce (Ketjap Manis), salt and pepper.
