In a bowl, combine all of the spice coating ingredients. Blend well. Dip each piece of the chicken into the spice mixture, place in a 9 x 13 pan.
Grill the chicken, over medium heat. About 7-8 minutes on each side, if boneless. More time needed if chicken has bones attached.
In another bowl, combine the butter and all of the lime butter ingredients. Mix well. Drizzle lime butter over chicken pieces on serving platter. Garnish with fresh lime slices. Or pass lime butter with the chicken.
-I used 4-5 large chicken breast halves, sliced in half, then pounded a little with a mallet to tenderize and thin out a bit for grilling .
