Chicken Tortilla Soup

From Averiecooks.com 

2 tablespoons olive oil
1 cup sweet Vidalia or yellow onion, peeled and diced small (about 1 medium onion)
1 large jalapeno pepper (about 4 to 5 inches long), diced very small (the seeds are where the heat is concentrated; included or discard them based on preference)
4 garlic cloves, peeled and finely minced
32 ounces (4 cups) low-sodium chicken broth
two 14.5-ounce cans diced tomatoes and juice (I used petite diced, no-salt-added)
one 15-ounce can black beans, drained and rinsed
2 cups shredded cooked chicken (use storebought rotisserie chicken to save time; or roast or cook your own chicken in a skillet)
1 1/2 cups corn (I used frozen straight from the freezer, fresh may be substituted)
1 tablespoon lime juice
1 tablespoon chili powder
2 teaspoons cumin
2 teaspoons salt, or to taste
1 teaspoon black pepper
1 teaspoon smoked paprika (regular paprika may be substituted)
1/4 teaspoon cayenne pepper, optional and to taste
1/3 cup fresh cilantro leaves, finely minced

diced avocado for serving, optional for serving
shredded cheese, optional for serving
sour cream, optional for serving

1. To a large Dutch oven or stockpot, add 2 tablespoons olive oil and heat over medium-high heat to warm. Add the onion, jalapeno, and sauté for about 5 minutes, or until vegetables begin to soften. Stir intermittently.
2. Add the garlic and sauté for 1 to 2 minutes. Stir intermittently.
3. Add the chicken broth, tomatoes and juice, black beans, chicken, corn, lime juice, chili powder, cumin, 2 teaspoons salt, pepper, smoked paprika, optional cayenne pepper, and bring to a boil.
4. Allow mixture to boil gently for about 5 to 7 minutes. If at any point the overall liquid level looks low or you prefer your soup to have more broth, add 1 to 2 cups of water; you’ll adjust the salt and seasoning levels at the end.
5. Add the cilantro and boil 1 minute.
6. Taste soup and add salt to taste. This will vary based on how salty the chicken broth, tomatoes, black beans, and rotisserie chicken are, and personal preference. Make any necessary seasoning adjustments (i.e. more salt, pepper, chili powder, cumin, cayenne, etc.).
7. Ladle soup into bowls, top with tortilla strips to taste, optionally garnish with avocado, cheese and/or sour cream; serve immediately.
