Chicken Taco Soup for Two

Heat oil in a heavy saucepan over medium-high heat until shimmering. Add onion and 1 1/2 tablespoons taco seasoning. Cook until onions are soft and translucent, 3 to 4 minutes. Stir in tomatoes with juice, chicken broth, and corn.

Sprinkle remaining taco seasoning over chicken pieces and add to soup. Stir to combine, cover, and cook until chicken is cooked through, about 5 minutes. Serve with tortilla chips, avocado slices, Oaxaca cheese, and sour cream.
