Preheat a skillet to medium-high heat with some olive oil. Combine the spices in a small dish with your fingers, then sprinkle all over both sides of the chicken.
When the skillet is hot, add the chicken pieces and cook for about 4 minutes on each side, flipping once, until the chicken is golden brown and nearly all the way cooked through. Remove the chicken to a plate to rest.
Add the salsa and stock to the skillet and reduce the heat to medium low. Stir and scrape the bottom of the skillet, then let the sauce reduce for about 10 minutes. Meanwhile, slice or dice the chicken.
Return the chicken and any juices to the skillet. Stir to warm the chicken and finish cooking for 1-2 minutes more.
Serve the chicken over rice. Enjoy!
