While picadillo cooks, fill large saucepan with water and place over medium-high heat to bring to boil. Once water is boiling, add plantains and cook for 8-10 minutes, until completely soft. Drain.
Place plantains in a food processor along with egg, ghee and salt and blend until completely smooth and combined.
Scoop 1/2 of the plantain puree into the greased baking dish and spread evenly throughout. Then top the plantain mixture with the picadillo, spread evenly and top the picadillo with the rest of the plantain mixture.
Place in oven to bake for 20 minutes. Once cooked through, let rest for 10 minutes to set before slicing and serving up with lime wedges and cilantro!
