Place the chicken on a cutting board and cover with plastic wrap. Gently pound with a meat mallet or rolling pin until the pieces are an even thickness.
In a small bowl, combine the chili powder, garlic powder, onion powder, dried oregano, kosher salt, black pepper, and chipotle chile powder.
Sprinkle the spice mixture evenly over both sides of the chicken pieces, rubbing lightly to adhere.
Heat the olive oil in a large skillet over medium-high heat until shimmering. Carefully place the chicken in the skillet and cook undisturbed for 4 minutes.
Flip the chicken, reduce heat to medium-low, and continue cooking until the thickest part registers 165°F, about 4 to 8 minutes more depending on thickness.
Transfer the cooked chicken to a plate or bowl and shred with two forks, a hand mixer, or by hand once cool enough to handle.
Return the shredded chicken to the skillet, add the broth, stir to combine, partially cover, and simmer gently on low for 5 minutes to blend the flavors.
Use the shredded chicken immediately for tacos, burritos, bowls, nachos, or other dishes.
