1. Place the sliced chicken in a bowl and add all of the ingredients for the marinade and toss well. Either use immediately, or refrigerate and marinate the chicken for an hour or overnight.
2. In a large frying pan sauté the mushrooms and set aside. In the same pan place the rest of the veggies and sauté until the veggies softened. When the veggies are ready add the mushrooms, seasonings and toss.
3. While the veggies are cooking, heat the griddle and grill the chicken until it is beautiful and golden.
4. When the chicken is grilled place it on your favorite bread or buns and top with the veggies.
