Add olive oil to a skillet over medium heat. Sauté the chopped onion until translucent, stirring frequently, about 5 minutes. Add minced garlic and stir for a minute until softened.
In a large bowl, mix the onion and garlic with the shredded chicken, cream cheese, cheddar cheese, spices, salt, chili sauce, lime juice, and fresh cilantro.
Fill each tortilla with a strip of chicken mixture, making a log. The filling should be well compacted so the taquitos stay put after bake.
Preheat the oven to 400°F (200°C).
Line a baking tray with parchment paper or foil. Arrange the taquitos in a single layer, seam side down. The more space you leave in between, the crispier they’ll get.
Bake for 10 minutes or until nicely golden and dry.
Serve with your favorite Mexican toppings such as guacamole or avocado, sour cream, fresh tomato, corn salsa or pico de gallo, refried black beans and lime wedges.
