Grilled Chicken Tacos with Spiced Mayo and Avocado Salsa

These Grilled Chicken Tacos with Spiced Mayo and Avocado Salsa are, hands down, my new favorite taco. As soon as I saw them I knew I had to make them. I could almost taste them just by reading the recipe.

I had to make a slight modification because I refuse to pay $1 for one lime when I can't even be guaranteed the lime will have any juice in it. Have you ever bought a lime and found it completely dry? How does that even happen? Lemons are still cheap so I just swapped it out. I also left out the hot sauce because Baby Girl isn't a fan of spicy food.

I prepared these on my indoor grill pan because, as I've mentioned before, we have a charcoal grill and getting that set up on a weeknight just doesn't happen. Since skewers won't fit on the grill pan I cut the chicken breasts in half lengthwise and grilled them before cutting into cubes. Same for the onion - I grilled it in rings and then chopped them. These tacos were so delicious we barely had enough leftover for one lunch the next day.

Grilled Chicken Soft Tacos with Spiced Mayo and Avocado Salsa
As seen on Seeded at the Table, originally from Weber's New Real Grilling

For the chicken:
zest of 1 lemon
1/2 teaspoon ground cumin
Salt & pepper
Olive oil
4 boneless, skinless chicken breasts, cut in half lengthwise
1 large yellow onion, peeled and cut into 3/4-inch rings

1/2 cup mayonnaise
Juice from 1 lemon
1 teaspoon hot sauce (optional)
1/4 teaspoon cumin

For the Avocado Salsa:
2 large avocados, peeled, pitted and diced
2 medium Roma tomatoes, seeded and finely diced
3 scallions, minced
2 tablespoons fresh lemon juice
1 tablespoon chopped cilantro
1/4 teaspoon hot sauce (optional)
8 taco or fajita-size flour tortillas

Preheat grill pan over medium-high heat.

In a large bowl or plastic food storage bag, combine the lemon zest, 1/2 teaspoon cumin, 1/2 teaspoon salt, 1/4 teaspoon black pepper and a few tablespoons of oil. Place the chicken pieces into the bowl or bag and toss to combine until evenly coated with the seasonings. In a separate bag or bowl, toss the onion rings with some oil, salt and pepper.

In a small bowl, whisk together the mayonnaise, lemon juice, hot sauce (if using), and 1/4 teaspoon cumin. Stir in water, 1 teaspoon at a time, until the mixture can be drizzled.

In another bowl, toss together the salsa ingredients and season with salt and pepper, to taste.

Add the onion rings to the grill pan and cook, turning often, until the onions are soft and blackened in spots. Remove from the grill to a bowl and cover with foil or plastic wrap. Add the chicken to the grill pan and cook 5 minutes on one side, then flip and cook another 4 minutes. Remove from the grill and let rest. Add the tortillas to the grill pan to warm and brown in spots, turning once. Cut the chicken and onions into bite-size pieces. Let everyone assemble their own tacos with the mayo and salsa.
