In a medium bowl, whisk the olive oil, lime juice, lime zest, chili powder, cumin, oregano, salt, and pepper together.
¼ cup olive oil, ¼ cup fresh lime juice, 1 tsp lime zest, 1 tbsp chili powder, 2 tsp ground cumin, ½ tsp Mexican oregano, 1 tsp kosher salt, ground black pepper
Pat the chicken dry and place them in a Ziplock bag.
1½ lbs. boneless, skinless chicken breasts
Pour the marinade over the chicken, zip the bag, and massage until the chicken is well coated. Place in the fridge for at least 1 hour or up to 6, to marinate.
In a large bowl, whisk the Greek yogurt, lime juice, cumin, salt and pepper. Add in the cabbage, cilantro, green onions, jalapeno and toss to combine. Refrigerate until ready to serve.
¼ cup plain Greek yogurt, 2 tbsp lime juice, ½ tbsp ground cumin, kosher salt and freshly ground black pepper, 2 cups shredded green cabbage, ¼ cup chopped fresh cilantro, 2 green onions, 1 jalapeño pepper
Heat your grill or grill pan over medium-high heat. Brush (or spray if using a grill pan) with oil. Grill the chicken until cooked through, about 5 minutes per side. Let the chicken rest for at least 5 minutes after grilling to seal in the juices. Place it aside on a plate and tent with foil to keep warm. Be sure to cook the chicken to an internal temperature of 165°F to avoid drying it out.
Grill the tortillas to warm through, 1-2 minutes per side.
8 corn tortillas
Slice the chicken into strips. Assemble the tacos with chicken, slaw, avocado, queso and optional salsa or hot sauce. Enjoy!
