Combine the shredded chicken, 1 1/2 cups of the cheddar cheese, 3/4 amount of the chopped jalapeno, and spices in a large bowl and stir to combine. Squeeze in the juice from half a lime, and mix. Set aside.
Heat a cast iron skillet over medium high heat and cook tortillas for 25-30 seconds on each side, until heated through and pliable, turning them regularly so as not to scorch. Place tortillas in a freezer bag to continue steaming and soften. Repeat with all the tortillas.
Place a scant 2 tablespoons of the meat and cheese mixture along the lower section of the warm softened tortilla and tightly roll up. Place the rolled taco, seam-side down pressing down gently to seal, on the cooling rack or parchment paper. Don't over-crowd, or else the sides won't crisp up.
Give all the exposed sides of the rolled tacos a light spray or brush of non-stick spray. Bake on the centre rack for 12 minutes. If they don't stay closed yet, keep them in this position for another few minutes till you can turn them over and they will stay closed.
Bake an additional 5-8 minutes, or until golden and the cheese is just bubbling.
Add the onion, 3/4 of the chopped jalapeño, cilantro, lime juice and zest, and 1/2 teaspoon each of salt and pepper.
Taste and add salt, pepper or lime juice if needed.
Feel free to use rotisserie chicken, leftover grilled or roasted chicken, or poach some chicken breasts. See the blog post for the instructions for poaching.
You can also replace the chicken with shredded beef or pork. Or why not sauté ground chicken, pork or beef instead, if that is what you have on hand.
If you want to use less chopped jalapeño for the taquitos, that's fine, go with what is good for your family.
Flour tortillas are softer and more pliable, and will be more tender. If using corn, use good quality, and ensure that they are completely pliable before placing in the freezer bag.
To freeze any taquitos, place rolled ones on a wax paper lined baking sheet. Freeze and then transfer to a freezer bag. These will keep in the freezer for up to two months. They can go directly into the oven, they will just require more time, about 25 minutes or so.
Feel free to reduce the amount of guacamole, unless you know you will be snacking on it during the week, it will store sealed in the fridge for up to three days.
