Sprinkle pork with 1/4 teaspoon salt and 1/4 teaspoon black pepper. Heat 1 1/2 teaspoons oil in a large Dutch oven over medium-high heat. Add half of pork to pan; cook 3 minutes or until lightly browned. Remove from pan with a slotted spoon. Add remaining 1 1/2 teaspoons oil to pan. Add remaining pork to pan; cook 3 minutes or until lightly browned. Remove from pan with a slotted spoon; keep warm.
Coat pan with cooking spray; add onion and bell peppers. Add wine, scraping pan to loosen browned bits. Return pork to pan. Add broth and next 4 ingredients (through bay leaf). Bring to a boil; cover, reduce heat, and simmer 1 1/2 hours or until pork is tender. Uncover and simmer 30 minutes or until sauce thickens. Discard bay leaf. Stir in remaining 1/2 teaspoon salt and remaining 1/2 teaspoon pepper. Sprinkle with parsley.
