I would recommend looking at the book list we have posted. It can help give you some ideas.

Personally, I'm all for easy. I have a rice cooker that makes cooking brown rice easy. One of my recent favorite things is to combine rice and beans in the rice cooker in the morning, then set a timer so the rice starts cooking before I get home and I have rice and beans cooked and ready. (I did this with adzuki beans which has a low cooking time). A pressure cooker is also a great way to cook something quick. You can also use a crockpot to set up a meal in the morning and come home to something cooked.
My husband and I also eat mass amounts of frozen veggies because they are so easy. You can steam them in the microwave by covering them with a wet paper towel or using a microwave steamer. I also reheat rice and beans that way.
Canned beans and tomatoes are also a life saver for me. A staple recipe for me is 2 cans of beans (2 different kinds), 1 can of diced tomatoes, some dried garlic, dried onion and whatever spices I'm feeling. Simmer that for 15 minutes and you got a pretty good part of a meal.
When I do cook, I tend to make large batches so that I have leftovers for lunches and dinners.
I even apply that philosophy toward salads. On Sunday nights, I take an hour to clean, chop and prepare salads for the following days. Since we eat 2 salads per day, in an hour, I make about 12 salads and prepare snack veggies (carrots, celery, radishes, etc) for lunches. It is also not unusual for me to spend some time making other dishes as well for the following days. Weeknights are fairly easy for me due to the fact that I can mass produce meals on the weekends.
