For the chicken marinade, mix all ingredients listed above in a blender.
In a separate bowl, pour the marinade over the boneless chicken thighs, making sure they are well covered. Set aside in the refrigerator for at least one hour.
For the salsa, start with charing up the veggies.
Mix all the salsa ingredients in a molcajete bowl or blender.
Once the chicken thighs are done marinating, throw them on the grill direct heat at 400 degrees. Cook for about 3 minutes per side or until internal temperature reaches 170 degrees.
Remove the chicken off the grill and chop up into cubes.
Warm up a few corn tortilla's directly on the grill grates.
To assemble, start with the warm tortilla's, layer on the chicken, salsa, some freshly chopped onion and cilantro and enjoy!
