Sure, but you still need some protein for your body so stick to baked,or grilled chicken and trim the fat before hand, or Tuna is also really good for you. If your a vegetarian can eat Kidney beans, Spinach,Beats Cabbage, Corn. And almost forgot Eggs,little bit of salsa tastes awesome. Don't be afraid to marinate the chicken to whatever you like, but keep it light.
