1. Preheat the broiler to high.
2. Heat a large skillet over medium heat. Add sausage and bacon to pan; cook 5 minutes or until lightly browned, stirring occasionally to crumble sausage. Remove mixture from pan using a slotted spoon; place in a bowl. Reserve 1 tablespoon drippings in pan; reserve remaining drippings for another use. Increase heat to medium-high. Add onion and next 4 ingredients (through minced garlic) to drippings in pan; sauté 3 minutes, stirring occasionally. Add onion mixture to sausage mixture.
3. Remove skin from duck breast; discard skin. Cut breast into 1/2-inch pieces. Return pan to medium-high heat. Lightly coat pan with cooking spray. Add duck breast; sauté for 3 minutes, turning to brown on all sides. Remove from heat.
4. Combine 1/2 cup beans, tomato paste, and stock in a food processor; process until smooth. Add pureed bean mixture, sausage mixture, remaining beans, and pepper to pan with duck; bring to a boil over medium-high heat. Cook 2 minutes. Spoon 1 cup bean mixture into each of 4 (8-ounce) ramekins lightly coated with cooking spray. Combine panko, parsley, and oil in a small bowl; toss. Divide panko mixture evenly among ramekins. Place ramekins on a baking sheet; broil 2 minutes or until browned.
