Heat 1 tablespoon olive oil in large dutch oven over medium until shimmering.
Add 1 diced onion and 1 teaspoon salt; cook, stirring constantly, until softened and starting to brown, about 8 minutes.
Add ½ cup chopped cilantro, 2 minced chipotles, 1 tablespoon adobo and 1 tablespoon cumin; cook 2 minutes.
Add 1 (32-ounce) box Pacific Foods Chicken Broth and 1 can diced tomatoes with green chiles; bring to a boil then reduce to a simmer and cook 10 minutes.
Meanwhile, for tortilla strips, add vegetable oil to a large stainless steel skillet until it measures ½ inch depth. Heat over medium until oil is shimmering. To test if oil is ready, drop 1 tortilla strip into oil; if it starts sizzling right away, oil is ready. Drop in a quarter of tortilla strips and, using tongs, separate any touching strips; cook until sizzling subsides and strips start to lightly brown, about 2 minutes. Using tongs or a slotted spoon, transfer fried strips to a paper towel-lined sheet and immediately sprinkle with salt. Repeat frying in batches with remaining strips.
Add 2 cups shredded cooked chicken, 2 cups frozen corn, 1 can black beans and 1 cup water; bring back to a simmer then season to taste with salt and serve with tortilla strips, Cotija, avocado and fresh cilantro.
