In a large saucepan with a tight-fitting lid, heat the olive oil over medium heat until hot.
Add chopped pork; sauté for 5 minutes or until golden on the outside and light pink in the center.
Remove from saucepan and set aside.
Add remaining ingredients (sweet potatoes through salt and pepper) and bring mixture to a boil.
Return the browned pork to the saucepan; cover and cook for 10 minutes or until pork is tender and cooked through.
