Heat a skillet over medium heat and add the ground beef. Cook, stirring and breaking it apart, until browned and no longer pink, approximately 5 to 7 minutes.

Add diced onion, green chilies, garlic powder, chili powder, and cumin to the browned beef. Continue cooking, stirring occasionally, until onions are softened and fragrant, about 3 to 4 minutes.

Stir in shredded cheese and cook until it melts completely, blending with the beef mixture to form a rich, cheesy filling.

Lay flour tortillas flat and place an even portion of beef and cheese filling in the center of each. Fold the sides over the filling and roll tightly to enclose fully.

Pour vegetable oil into a deep skillet to a depth of 2.5 to 5 centimeters and heat over medium until shimmering. Carefully place rolled chimichangas seam-side down and fry 3 to 4 minutes per side until golden brown and crisp.

Remove chimichangas from oil and drain on paper towels to absorb excess oil. Serve hot accompanied by sour cream and salsa.
