Any way to add stroke to a Polygon2D?

Question

I'm looking for a simple way to add black stroke to Polygon2D. I know that you can duplicate the polygon and increase the size a bit to imitate a stroke, but that's not really good, especially for performance. I'm honestly surprised there isn't just a single stroke option for Polygon2D. Anyone know how to do this the best way?

Put a Line2D over it.
