In a medium mixing bowl, combine the cooked shredded chicken, shredded cheddar cheese, softened cream cheese, and sour cream. Mix thoroughly with a fork until well blended and creamy.

Add garlic powder, onion powder, cumin, chili powder, salt, and pepper to the chicken mixture. Stir well and adjust seasoning as needed.

Lay a small flour tortilla flat. Spoon 2-3 tablespoons of filling onto the lower third of the tortilla. Tightly roll the tortilla away from you, tucking in the sides.

In a large skillet, pour enough vegetable oil to cover the bottom with about 1/2 inch depth and heat over medium-high for 5-7 minutes.

Carefully place the rolled taquitos seam-side down into the skillet. Fry for about 2-3 minutes until golden brown and crispy.

Use tongs to remove the taquitos from the skillet and place them on a plate lined with paper towels to absorb excess oil.

Arrange the fried taquitos on a serving platter and serve warm with your choice of salsa, guacamole, sour cream, or chopped cilantro.
