In a large bowl, combine the ground beef, onion, mashed potatoes, garlic powder, cumin, paprika, oregano, salt, and pepper and mix until thoroughly combined.
Divide the mixture into 4 equal portions and form into patties.
Heat a large skillet over medium-high heat and add enough olive oil to coat the bottom of the skillet.
Once the oil is hot, add the patties to the skillet and cook for about 5 minutes per side, or until the burgers are cooked through.
Serve the burgers on buns with your favorite condiments, such as ketchup, mustard, mayonnaise, lettuce, and tomato.
