Line the crock pot with a disposable liner, or spray with nonstick cooking spray. Add chicken and season it with salt and pepper.
To make the sauce: In a medium bowl, add all the ingredients to make the sauce and mix. Pour over the chicken in the crock pot.
Cover the pot and cook on LOW for 3-4 hours or on HIGH for 1½-2 hours. Stir once halfway through.
Add the bell peppers, peas, edamame, and carrots.
Place the cornstarch and cold water into a small bowl and stir until smooth. Add it to the crock pot and mix. Cook on High Heat for about 30 minutes until the sauce thickens.
Meanwhile, cook the noodles according to the package. Drain.
After the sauce has thickened, add the noodles. Stir in the noodles to coat them with the sauce. Add any garlic salt, salt, and pepper to taste.
Garnish with sesame seeds and serve hot.
