In a bowl, combine softened cream cheese, sour cream, diced cooked chicken, shredded cheddar, and pepper jack cheese. Mix until smooth.

Take a flour tortilla and spread about 2 tablespoons of the filling in a line down the center.

Roll the tortilla tightly around the filling, tucking in the sides as you roll.

Heat oil in a frying pan over medium-high heat. Carefully place the rolled taquitos seam-side down into the oil.

Fry for 2-3 minutes on each side or until golden brown and crispy. Remove them from the oil and place on a paper towel to drain excess oil.
