Easy chicken tacos with a delicious corn and avocado topping!
Trim the chicken breasts of fat and pound them to even thickness to ensure even grilling. You can also slice them evenly in half widthwise for a quicker grill. Place the prepared chicken in a large ziplock bag and set aside.
In a small bowl whisk together 1/4 cup olive oil, 1 teaspoon lime zest, 1/4 cup freshly squeezed lime juice, minced garlic, cumin, paprika, chili powder, and salt + pepper (I use about a teaspoon of each). Once the mixture is well combined, remove 3-4 tablespoons of the mixture and reserve for later.
Preheat a grill to medium-high heat (about 450 degrees F.) Generously oil the grill (I drench a rolled-up paper towel in vegetable oil and, holding it with tongs, rub it over the grill grates. Don't skip this step.) Husk the corn and rub olive oil over the corn. Sprinkle the corn lightly with salt and pepper. Place the corn on one half of the grill.
Remove chicken from marinade and discard remaining marinade. Grill the chicken (on the other half of the grill) turning once halfway through grilling, about 4-6 minutes per side (until the thickest part of the chicken registers 165 degrees F.). Baste the chicken with the reserved marinade as you grill and after flipping. Transfer the chicken to a plate and cover with foil. Allow the chicken to rest for a few minutes so the juices can re-distribute. Thinly slice the breasts. As you baste the chicken, flip the corn too. Remove the corn when grilled to your liking (about 15-20 minutes, turning every 5 minutes) (Alternative corn preparation: see note)
In the last 2 minutes of grilling, add the flour or corn tortillas to the grill. Spray both sides of the tortillas with cooking spray, lightly sprinkle with salt, and then place on the grates for 30-45 seconds, flip and leave on for another 30-45 seconds. Remove and immediately fold into taco shape and set aside to slightly cool.
Allow grilled corn to cool and then slice it off the cob. Toss the grilled corn with the chopped avocado, thinly sliced green onions, finely chopped cilantro, and finely chopped jalapeno. Add a tablespoon of fresh lime juice (optional) and toss together. Set aside.
For the sauce: whisk everything together until smooth and combined. Taste and adjust to personal preference (additional salt, pepper, sriracha, etc.)
Fill up the grilled/warmed tortillas with thinly sliced cooked chicken, a generous spoonful of the corn-avocado mixture, and a good spoonful of the sauce. Additionally add extra lime juice, cilantro, and/or cotija cheese. Enjoy!
Alternative #1: use pre-roasted canned corn -- drain and allow to dry. Alternative #2: use regular canned corn: heat a large cast iron skillet on medium high heat for 3-4 minutes or until very hot. Drain corn and place in a single layer and cook for about 5 minutes stirring once in between or until browned. Avoid stirring too often as this will keep the corn from getting a good roast.
