I've never seen such a GOOSE in our little Chinatown. I know what I'd be doing if I were inviting friends anytime during the Solstice-Christmas-New Year's holiday season, if I lived in Toronto.
This Guardian story about a Perón-Perón café mentioned an Argentine version of shepherd's (or cottage) pie. I've also had the same thing made by friends from Chile, so I guess it is the whole Southern Cone.

I posted the first version I found. It's in (simple) Spanish, but running it through Google translate will make it understandable and save me unwelcome free work: http://recetasdeargentina.com.ar/pastel-de-papas
About the only instruction it failed to translate was descarozar, (to stone or pit fruit).
