In a large heavy saucepan over medium heat, cook bacon until brown and crisp, about 10 minutes. Remove with a slotted spoon; drain on paper towel. Pour off all but 2 tablespoons of drippings. Add scallops and brown well on all sides; remove to a paper towel. Add onion to drippings and cook until just softened. Add potatoes, green bell pepper and garlic; cook 5 minutes, stirring often. Add vegetable stock and bring to boiling; reduce heat and simmer 10 minutes.
Add cream, scallops and corn; cook uncovered until potatoes and scallops are tender.
Just before serving, add parsley and reserved bacon; season to taste with salt and pepper.
