Heat 1 tablespoon of the oil in a skillet over medium heat. Add onion and garlic; cook and stir for 1 to 2 minutes. Add beef and taco seasoning and cook until beef is brown and crumbly, about 5 minutes. Drain extra liquid from skillet.

Heat remaining oil in a large skillet over low heat.

Meanwhile, spread a teaspoon of queso sauce onto a tortilla as glue. Add 1/4 cup browned beef in the center and top with 2 tablespoons cheese. Roll up tortilla and secure roll with a toothpick. Repeat for remaining tortillas.

Carefully place rolled up tortillas into the hot oil. Fry until golden brown, about 2 to 3 minutes.
