Place 1 slice cheese substitute on one slice and dressing and sauerkraut on other slice. Allow vegan bread to toast and cheese to melt. When cheese has melted, place strips of tempeh on the vegan bread with sauerkraut and dressing and cover with the melted cheese vegan bread. Continue process with remaining slices of vegan bread and serve :)
