In a small jar, add the mayonnaise, sour cream, pickled jalapenos, ½ teaspoons of sugar and paprika, and ¼ teaspoon of garlic and onion powder. Use a hand blender or a food processor. Blend for 1 minute or until all the ingredients are well combined.
Cut the chicken
Cut the tenderloin of the chicken breast. Then cut the chicken breast so that the thinnest part of the chicken is about 2 third of the cut. The smaller side of the chicken should be the thickest part of the chicken breast. (See step image in post for reference).
Lay the chicken pieces flat on a surface, cover with plastic wrap, and pound the chicken until each piece is about ½ inch thick.
Brine
In a big bowl, add the water, 1 ½ tablespoons of salt, ½ tablespoon of sugar, 1 teaspoon of baking soda, and mix. Add the chicken and let it sit for only 15 minutes (*if you leave the chicken longer, it will become rubbery). Rinse the chicken 2 times with cold water and remove any excess water.
Bread the chicken
In a bowl, mix the flour, cornstarch, garlic powder and onion powder, black pepper, and 1 tablespoon of salt. Mix until all the flour and the seasonings are well combined. Prepare an extra bowl of water to dip the chicken in.
First, bread your chicken and remove any excess flour. Then dip the chicken in the water and then add it to he breading to cover it again with the flour mixture. Press down on the chicken and flour so it sticks better to the meat. Flip the chicken and press on to with flour. Softly shake off any excess flour. Repeat with the other piece of chicken.
Fry
In a medium-size pan, add the oil and set the heat to medium-high. Wait for the oil to get hot, and then add both chicken pieces. Fry for 12 minutes while flipping a couple of times.
Remove the chicken onto a baking rack so it can drip off the excess oil.
Assemble sandwich
Toast the bread. Spread one tablespoon of sauce on the lower bun. Add the chicken and pour 1 tablespoon of sauce over it. Add the onions, cheese, corn chips, tomato, lettuce, and top bun. Buen provecho
Notes
Brine- The brine is important because it will make the chicken more tender, and it will also add flavor from the inside out.
Sauce- You don't have to use the creamy jalapeño sauce, but I highly suggest it.
Toppings- You can change the toppings to your liking. But for me, the chips are really good.
Prepare ahead of time. You can leave it in the oven at about 200F for no more than 20 minutes.
