Melt Butter (1 tablespoon) in a Dutch oven or heavy pot over medium-high heat. Sprinkle Boneless, Skinless Chicken Thigh (16 ounce) evenly with Kosher Salt (1/2 teaspoon) and Freshly Ground Black Pepper (1/4 teaspoon). Add chicken thighs to the pan; sauté for 3 minutes on each side or until browned. Remove chicken thighs.
Add the Onion (2 cup), Carrot (1 cup), and White Miso Paste (1 tablespoon) to the pot; sauté for about 2 minutes, stirring occasionally. Add the Dry White Wine (1/2 cup); cook for 1 minute, scraping the bottom of the pot to loosen any browned bits.
Chop the chicken thighs into bite-sized pieces then to the pot. Tie twine around Fresh Poultry Herb Blend (1 ounce) to secure, forming an herb bouquet.
Add the herbs, Chicken Stock (6 cup), Sliced Celery (1 cup) and Chopped Boneless, Skinless Chicken Breast (1) to the pot. Bring to a boil, then reduce heat and cook for 10 minutes.
Cut up the Fresh Lasagna Sheets (4 ounce) to your liking.
Remove and discard the herb bouquet. Check for seasoning and add more salt or pepper, if desired. Add the pasta; simmer for 4 to 5 minutes or until pasta is done. Before serving, sprinkle with the chopped Scallion (3 tablespoon).
