Preheat oven to 400°F. Spray a casserole dish, or a large baking sheet with oil and set aside.
While the oven is heating up, wash, peel (if desired) and cut potatoes into chunks.
Sprinkle with salt, pepper, some chopped rosemary and drizzle 1 tablespoon olive oil over.
Mix everything together and spread in your baking dish.
Bake for about 15 minutes or until we finish preparing the chicken.
In a small bowl combine the remaining oil with the rest of the marinade ingredients well and taste to adjust seasoning.
Cut chicken into 1 inch cubes and place in a bowl. Pour the marinade over and mix well.
Take the dish out of oven and mix in chicken.
Cover with foil and return to oven for 30-35 minutes or until chicken is done.
Uncover, spread the cheese over and return to oven for 10 minutes until cheese melts and bubbly.
