Thai Chicken Peanut Noodles

I have tried many recipes for this and haven't always been impressed but I loved this one, it was very good. I found this recipe on the sister's cafe blog.

1 lb whole wheat thin spaghetti noodles
1 garlic clove, peeled
1 (1 inch) piece of fresh ginger, peeled
½ Cup smooth peanut butter
2 Tablespoons sesame oil
¼ Cup soy sauce

2 Tablespoons brown sugar
1 Tablespoon rice vinegar
1 scant teaspoon crushed red pepper flakes
1 Cup hot water
2 Tablespoons extra virgin olive oil
½ Cup finely chopped white onion
½ Cup finely chopped red or orange bell pepper
2½ - 3 Cups cooked, shredded chicken breast
¼ Cup finely chopped cilantro leaves
1/2 teaspoon salt, or to taste

Cook chicken and shred.
Place garlic and ginger in food processor until well chopped. Add peanut butter, sesame oil, soy sauce, brown sugar, vinegar and red pepper flakes. Pulse until well combined and slowly add hot water. Set aside. If you don't have a food processor or the right attachment for it then the blender works great too.
Place olive oil in hot skillet over medium heat. Saute onion and bell pepper for 5 minutes or until softened. Stir in chicken breast, cilantro and salt. Stir until heated through.
Add sauce and chicken mixture to noodles. Toss to coat and garnish with peanuts and sesame seeds if desired.
