Vegetable Noodle Soup

Ingredients
2 tablespoon(s) cooking oil 
2 onions, chopped 
3 carrots, halved lengthwise and cut crosswise into 1/2-inch slices 
2 ribs celery, cut into 1/2-inch slices 
1 1/2 quart(s) canned low-sodium chicken broth or homemade stock 
1 3/4 cup(s) canned diced tomatoes with their juice (one 15-ounce can) 
1 tablespoon(s) tomato paste 
1/2 pound(s) potatoes, peeled and cut into 1/2-inch dice 
1/2 pound(s) green beans, halved 
1 1/4 teaspoon(s) salt 
3 ounce(s) fine egg noodles (about 1 cup) 
1/3 cup(s) chopped fresh parsley 

1. In a large saucepan, heat the oil over moderately low heat. Add the onions, carrots, and celery and cook, stirring occasionally, until the vegetables start to soften, about 10 minutes. Stir in the broth, tomatoes, tomato paste, potatoes, green beans and salt. Bring to a boil. Reduce the heat and simmer, partially covered, until the vegetables are almost tender, about 20 minutes. 

2. Stir in the egg noodles. Bring the soup back to a simmer and cook until the vegetables and noodles are tender, about 5 minutes. Stir in the parsley. 

3. Variations: Feel free to mix and match vegetable combinations according to what you like and what you have on hand. Other excellent soup vegetables include: fennel, celery root, cabbage, parsnips, turnips, peas, zucchini, squash, shredded greens, corn, lima beans and bell peppers.
