In a Dutch oven heat 2 tablespoons of olive oil.
Add the onions, onion, green pepper, and jalapeno pepper. Saute over medium heat until the vegetables are slightly tender.
Stir in the diced tomatoes, roasted green chiles, cilantro, cumin, and oregano. Add the cooked chicken and mix in.
Add the broth and lime juice, mix well. Bring to a boil. Once it boils reduce heat and simmer for about 30 minutes or until vegetables are tender.
While the soup is simmering make the tortilla strips.
Cut tortilla shells into about 1/4- inch strips. Heat about 3 tablespoons of olive oil in a skillet. Fry the strips in small batches until golden brown. Salt lightly.
Add additional as needed.
Serve the tortilla strips in the soup. Top with shredded cheese, additional slices of jalapeno, lime slices, or what you desire.
