I didn't make quite as much chicken as the recipe calls for (because it's just me, the roommate, and a meal or two of leftovers), and I adapted the recipe to cook the chicken in the oven instead of on a grill. I set the oven to 400 degrees Fahrenheit, and after about 22 minutes my average-sized chicken breasts were cooked all the way through. I stuck them back under the broiler once I'd put the blue cheese on top to get that melted, and the whole thing came out moist, tender, and delicious.
I served up some lemon butter potatoes and green beans on the side; for that dish, I modified a Deen Bros. recipe (replace oil with butter and garlic with lemon zest). The whole well-balanced meal tasted (and looked!) fantastic and colorful.
