The only recipe for Patele (or pastele) stew I have come across is the one in the Alohaworld Ono Recipe collection: Patele Stew

Most of the time pasteles are eaten alone (like tamales) and are steamed. In the Alohaworld Recipe, you take 4 premade pastels and break them into pieces and stick it into the stew so they absorb the liquid. They key is getting those pasteles (and those are time consuming to make). The "stew" part (the chicken, pork, tomatoes and spices) are like any other kind of tew.
