Asian soup with pork

This is probably the only recipe on this blog (so far) that came straight out of my head. I was really craving a soup like this so I bought some ingredients. I checked out some website for recipes, but I didn't like most of the ingredients listed. It turned out so good I immediately went back and thought through everything I did so I could replicate it. Here's the recipe:

INGREDIENTS:
1 bottle Kikkoman, Teriyaki garlic & green onion marinade (found at most grocery stores)
1 boneless pork roast (I bought this pre-packaged in the meat section)
1 TBSP canola or vegetable oil (instead of olive oil)
1/2 tsp celery salt
3 -4 carrots peeled and cut julian style
3 celery stalks, trimmed and diced
2 garlic cloves minced
1 or 2 TBSP soy sauce
2, 32 oz boxes of chicken broth
1 bag bean thread noodles (a Chinese clear noodle, but you can use any noodle you wish. Try the international isle at the food store.)
4-5 scallions or green onions, diced

1. Preheat oven to 400. Heat a skillet and pour a little bit of the Teriyaki sauce in the pan. Add the pork roast. Cook for 5 minutes on each side, you only want to brown it in the sauce. Place the pork in an oven-safe dish and pour about 1/2-3/4 cup Teriyaki sauce over the roast. Cook for 45 minutes in the oven or until no longer pink in the middle.

2. Meanwhile, heat a stock pot with canola oil. Add celery, carrots and celery salt. Cook about 5 minutes stirring occasionally. Add garlic and cook an additional 2 minutes. Add soy sauce and chicken broth and bring to a boil. Once boiled add noodles and cook for about 10 minutes or until tender.

3. Once the meat is cooked let it sit for at least 5 minutes to let the juices collect. I promise this is worth it. Slice the meat into thin strips. Ladle the soup into bowls. Place the pork on top of the soup and garnish with green onions.

NOTE: Cilantro would be a great addition to this soup if you like the flavor. You can add it to the broth in the last few minutes of cooking the noodles of just place it as a garnish on top of the soup.
