Place the chicken hearts, olive oil, salt, pepper, garlic powder, onion powder, smoked paprika, and cumin in a large bowl.
1 pound chicken hearts, 2 tablespoons olive oil, 1 teaspoon Diamond Crystal kosher salt, ¼ teaspoon black pepper, ½ teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon smoked paprika, ½ teaspoon ground cumin
Use a large spoon to mix everything together, coating the hearts with the oil and seasonings.
Heat a large, heavy frypan over medium-high heat for about 3 minutes.
Add the seasoned hearts. Cook, stirring often, until browned and cooked through, 5-7 minutes. If the pan becomes too hot, lower the heat to medium.
Divide the hearts between four plates. Drizzle them with the pan juices, garnish with chopped parsley, and serve.
2 tablespoons parsley

Notes
Seasonings, especially salt, are guidelines. Adjust to taste.
Make sure not to overcook the hearts, or they will turn out tough. When properly cooked, they're nice and tender, if a bit chewy. Having said that, keep in mind that the USDA says they should reach an internal temperature of 165°F.
The hearts will release liquid into the pan as you cook them. The liquid will mix with the olive oil and spices. It's delicious! So, make sure to serve the hearts with this pan sauce. You can serve the hearts on a bed of something to absorb the sauce (rice, cauliflower rice, or mashed cauliflower) or serve them in a bowl with a spoon.
You can keep the leftovers in a sealed container in the fridge for up to 3 days. Reheat them covered in the microwave at 50% power. You can also freeze the leftovers for up to three months. Thaw them overnight in the fridge and then reheat them covered in the microwave.
