Chicken, Zucchini, and Tortellini Soup

I was browsing the aisles of the supermarket this weekend, and one refrigerated case had chicken breast, tortellini, and zucchini in it. The combination of those ingredients seemed meant for a soup, so I developed this recipe last night. It's fairly easy and comes together quickly. The longest part is chopping the vegetables.

Ingredients

1 Tbsp. olive oil
2 carrots, sliced into  1/4 inch slices
1 celery rib, diced
1 onion, chopped fine
1.5 tsp. salt , divided
1/2 tsp. black pepper
2 garlic cloves, minced
1/4 c. dry white wine
4 c. chicken broth
1 lb chicken breast, cut into 1 inch pieces
1 zucchini, quartered lengthwise and sliced into 1/2 inch slices
1 nine ounce package of refrigerated tortellini

Directions

1. Heat 1 tablespoon of olive oil over medium high heat. 
2. Add carrots, celery, and onion. Add 1/2 tsp. salt. Cook for 6 minutes, stirring occasionally, until vegetables are just beginning to brown. 
3. Add garlic and cook for another 2 minutes. 
4. Add the wine, scraping any brown bits from the bottom of the pan. 
5. Add the chicken broth and bring to a boil.
6. Sprinkle chicken breast with remining salt and pepper. Add to the broth.
7. Reduce to a simmer, cover, and cook for 10 minutes. 
8. Add the zucchini and tortellini, then cook for another 10 minutes uncovered. Serve.
