Chef tips
For a more rustic texture, leave a few small chunks in the mashed potatoes. If the filling seems too wet, cook it for 1 to 2 extra minutes before assembling the bake.
Substitutions
You can replace the chicken with diced turkey. Chanco cheese can be swapped for low-moisture mozzarella or another mild melting cheese. If you cannot find chuchoca, use toasted coarse cornmeal, though the flavor will differ.
