So much depends on your personal taste, time, and budget. I get sick of plain grilled chicken and brown rice real fast. There are so many relatively healthy ways to make chicken if you are creative, but still, it is good to have other meats in your rotation.
With a little preparation and planning you can have some pretty damn good cooked meals with ease. It is sad, but I would guess 90% of society rarely really cooks anymore. It may due in part to being busy or laziness, but cooking with fresh ingredients unfortunately is also a lot more expensive than eating the processed stuff or carb based meals.
The world is so overpopulated that everyone could not really even eat lots of lean meat, fruits, and vegetables if they wanted to. No fear, this country and many other prosperous countries are not giving up their carb addiction anytime soon. Feel blessed you live in America and are not on food stamps.
The truly gourmet meals tend to take a little more money and time. The complex sauces made from scratch tend to be really time consuming in these dishes. You can always modify recipes you see on TV to make them healthier and quicker. Think of all the different ethnic foods and the different core spices they use in their dishes to create your own recipes.
I am lucky in that I like strong flavors and spices, but much of that is acquired. Spices tend to have few if any calories, and you need less quantity of strong cheeses and other strong flavored ingredients to feel satisfied. Some people love the crockpot, which helps to make less expensive lean cuts of meat tender. Marinades are also great for this.
Remember, even Berardi says the people in the best shape tend to eat fairly boring. You will have some monotony even with great tasting recipes made with fresh and flavorful ingredients.
You really only need a few easy recipes you really love and you can put new ones in the rotation as you have the time or get sick of the old ones in your rotation.
Once you have your favorites it is easy to have the needed ingredients on hand, and it will become second nature to you and you will be able to cook them with out really even thinking. I was short on time tonight and had chicken pesto on barilla plus pasta with grape tomatoes and spinach.
The pesto was store bought. It took less than 30 minutes and that included grilling the chicken and boiling the water. Plain grilled chicken and brown rice would have taken almost the exact same amount of time to cook.
In the beginning it takes some effort, but it pays off. People can list recipes which is a great help, but like many things you have to find what works for you. There are plenty of recipes mentioned on this site. Chef Lisa is a great resource.
As mentioned read Berardis articles. You could also purchase his precision nutrition. Mike Roussell also just put out a book with many recipes.
