In a skillet, cook the ground beef until browned.
Drain excess fat, then mix in taco seasoning according to the package instructions. Let cool slightly.
Warm the tortillas to make them pliable.
Fill each tortilla with a portion of the seasoned beef, a scoop of refried beans, and a sprinkle of cheddar cheese.
Roll each tortilla tightly, folding in the sides to create a secure package.
Heat oil in a large pan over medium heat.
Carefully place the chimichangas in the hot oil and fry until golden brown and crispy on all sides. Remove from the pan and drain excess oil on a paper towel-lined plate.
Serve hot with sour cream and salsa on the side. Enjoy!
