Heat oil in a Dutch oven over medium-high heat. Add bell pepper, carrot, and onion; cook 10 minutes or until tender, stirring occasionally. Add paprika and garlic; sauté 1 minute. Add 3 cups broth and black pepper; bring to a boil. Cover, reduce heat, and simmer 20 minutes or until the vegetables are tender.
Place one-third of vegetable mixture in a blender. Remove center piece of blender lid (to allow steam to escape); secure blender lid on blender. Place a clean towel over opening in blender lid (to avoid spills). Blend until smooth. Pour into a large bowl. Repeat procedure with remaining vegetable mixture.
Return pureed vegetable mixture to Dutch oven; stir in remaining 2 cups broth and pumpkin. Cook over low heat for 10 minutes or until thoroughly heated, stirring frequently. Remove from heat; stir in juice. Ladle 1 cup soup into each of 7 bowls; top each serving with about 1 teaspoon pumpkinseeds and about 1/2 teaspoon parsley. Serve immediately.
