On roasting chickens:
There are two ways to roast a chicken and get a moist, tasty bird. The principle behind both is moisture, moisture, moisture!
Option A is a bit more time-consuming, but produces a chicken with deliciously crisp, brown skin. For this, take the chicken, and place it breast-up in a baking dish or pan that you’ve coated with a thin layer of either oil (olive is best) or butter. Pour a little oil or melted butter (or both) over it. You don’t need much–just 2-3 tablespoons. Add your herbs–I’d suggest thyme, tarragon, and sage, a light dusting of each, and ditto salt and pepper. You could also mix 2-3 tablespoons of lemon juice with the butter or oil, and then sprinkle some crushed rosemary and salt and pepper over the chicken. Put it in the oven, which you’ve preheated to 350 degrees. Before you throw away the wrapper the chicken came in, make a note of the weight. You’ll be cooking the chicken for approximately 18-20 minutes per pound, or until a thermometer inserted in the thickest part of the thigh reads 165 degrees. Every 15-20 minutes, open the oven, take a big spoon, and dip up the butter/oil/chicken drippings mixture from the pan, and pour it over the chicken. The idea is to keep a layer of that stuff over the chicken at all times. Like I said, more time-consuming, but the skin that comes off a bird cooked like that is the
best.

Not especially healthy, of course, but…yummmm!
Option B is much like Option A, except that you put the chicken in a greased pan with the seasonings like in option A, but use for the pan either a dutch oven (think a wide, heavy, ovensafe pot with a lid), a casserole with a lid, or a deepish pan that you can cover with aluminum foil. Once more, cook for 18-20 minutes/pound or until a thermometer inserted in the thickest part of the thigh reads 165. Because the chicken is covered, it’s almost more steamed than roasted–water can’t escape much from the inside of the pan, so the chicken won’t get dry unless you roast it a ridiculously long time.
Option B, crockpot edition is the easiest of all, though again, it means not having as tasty skin. Take the chicken, and put it in the crockpot. Drizzle with a little oil or butter. Dust it with seasonings. If you want, you could throw some carrots under the chicken. (Some people suggest potatoes, but they always come out really mushy for me like this, so I’m not a fan.) Put the lid on the crockpot, and set it on “low.” Go to work. Come home, and enjoy the fact that dinner is already made for you. You could even get the chicken ready the night before: just put it and the seasonings and so on in the ceramic dish part of the crockpot, but set that in the fridge, and the next morning, all you have to do is set it in the crockpot pan, turn the switch, and go to work. I like recipes like
this . Lots of flavor!
I’m told you can also put a crockpot chicken under a broiler for 4-5 minutes if you want the skin crisped up, but I haven’t tried that so can’t really comment on it.
Insofar as processed food goes, you can drive yourself mad trying to follow every dietary recommendation out there.

Everything in moderation, including moderation! I wouldn’t suggest for a second a diet consisting entirely of white flour, but dipping a chicken thigh in it before cooking it on the stove can keep it moister and more flavorful at the expense of eating a total of, what, half a teaspoon of flour, max? Likewise, applesauce is, well, cooked apples. You can make your own, of course, if you want to (there are some quite good crockpot recipes out there, and you could freeze single servings of it in sandwich-sized bags stacked flat in the freezer), but as processed foods go, I’d avoid, say, “fruit-flavored snacks,” but not unsweetened applesauce whose ingredients are apples, water, and citric acid. (Citric acid is Vitamin C, and is often added to products with a high amount of fruit of the kind that browns when exposed to oxygen. Citric acid prevents this.) I’d also eat some fresh apples. Balance is the idea here.
Another great and healthy food to batch cook is brown rice. You can cook several servings at once, and use it for a lot of things. One day, you might eat it with chicken. The next, you might throw a cup of it in a pan with some soy sauce, a couple of eggs, some chopped vegetables, and a bit of ginger and garlic and have some
awesome fried rice. Then you might have the rest of it in a tortilla with some beans as a burrito a couple of days later.
