Poach chicken. Place chicken in a saucepan, and cover with water. Bring to a boil, then reduce the heat to simmer for 10-12 minutes or until the internal temperature of the chicken reaches 165°F/74°C.

Transfer the chicken to a cutting board or bowl, and shred it with 2 forks.

In a skillet, heat oil and sauté the onion until it’s soft and translucent (3 minutes).

Add the garlic, and sauté for 30 seconds. Add cumin, oregano, chili powder, and salt. Cook for 1 more minute.

Add salsa, and just mix it in (if necessary, you can add a splash of water) and let it warm up.

Add the chicken, and mix it in with the sauce. Simmer for 2-3 minutes.

Serve in warmed up tortillas or taco shells with your favorite toppings.
