Cube chicken and combine with garlic, juice of limes, honey, and a heavy pinch of salt and pepper. Let marinade for 15 minutes. (Now would be a good time to dice the onion, slice the avocado, chop the pineapple, and salt the slaw mix.)
Once marinaded, grill or saute the chicken over medium heat until cooked, ~10 minutes. Once cooked, lightly toast tortillas and serve tacos topped with onion/avocado/pineapple/slaw mix.
