How to Make It
Place bacon in a Dutch oven over medium-high heat; cook 5 minutes or until crisp. Remove bacon with a slotted spoon; crumble.
Add onion, celery, carrot, and garlic to drippings in pan; sauté 5 minutes or until slightly tender. Add miso, salt, pepper, and peas to pan; sauté 2 minutes, stirring constantly. Add stock and bay leaf; bring to a boil over medium-high. Partially cover, reduce heat to medium-low, and simmer 1 hour or until peas are tender. Discard bay leaf. Stir in bacon.
