I've grilled my chicken all the way through my diet, I used to use garlic powder and mrs. dash, though now that my diet has gotten more strict, I use tamaric powder and pepper.
Grilling is fine. I don't have a grill, so, in turn, I put my chicken breast in a heated skillet and turn it a bunch of times. (not letting it burn- about 1 min or turning) then I take the skillet and stick it in a pre-heated over (500). For about 10-15 min, depending on size of chicken breast. Really juicy and tender. I love it. (my g/f taught me)
