Preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper.

In a mixing bowl, combine shredded chicken, cream cheese, cheddar cheese, salsa, garlic powder, onion powder, cumin, salt, and pepper. Mix until well incorporated.

Wrap tortillas in a damp paper towel and microwave for about 15 seconds to warm them.

Spoon 2-3 tablespoons of the filling onto the center of each tortilla, roll tightly, and place seam-side down on the baking sheet.

Lightly spray or brush taquitos with olive oil, then bake for 15-18 minutes until golden brown and crispy.

Remove from oven and cool slightly. Serve warm with sour cream, guacamole, or salsa.
