This is a fun and timely discussion. Today, I ate out for lunch. It was an impromptu going away lunch for a coworker at a Chinese restaurant. I ended up sitting with four others, and we agreed that four items would be fine for the 5 of us. I let them order.
It was glorious! I am female, and I've taken on the bulk of the cooking and meal planning for my family. It's exhausting, and it definitely takes up a lot of "brain power". When my second child was born, and brain power was at a minimum, I had a weekly rotation. I cooked two big meals on the weekend and we ate them until we ran out. I made a third meal big enough for lunch. And Weds was crock pot day, because that's when we were out of the 2 big weekend meals.
I rotated lunch. So, one week, lunch was pasta. Next week it was soup. Next week bulk-made burritos, next week sandwiches.
Now, though, cooking for four, it's hard. Food doesn't last long. I gave up and let my older son get the school lunch. One less thing to think about.
We used to be members of a CSA, but it ended last year and hasn't started again due to drought. Just this week we started getting a produce box - similar, but they deliver.
Goodness, it's tiring, no? I look at everything we get and have to figure out what to do with it. Then I have to prep it. It's not automated at all. Shopping is automated. Buy a bunch of vegetables - eat salads and steamed or roasted veggies with protein and a carb. But the produce box? Okay, figure out what to do with celery, carrots, red cabbage, lettuce, broccoli, etc. etc. Oh, and prep it all at the beginning of the week, or most of it. I love the freshness of the CSA/ box, but it does make my brain hurt. I used to love it when I was working part time, but with a job and kids it's HARD.
For a single person, I would recommend considering:
http://mybodymykitchen.com/This is just an example of meal prep methods. Meal prep is common in families and with people who are trying to lose weight, or get fit, or whatever. It does require "work" but automates much of the rest of life. So in the example above, this guy cooks, say, 5 servings to 6 servings of a meal. He preps 2 different ones each week. This allows for one for lunch and one for dinner. Of course, if you do it right (eat out a few times, eat sandwiches, or prep 3 to start), then you can get a nice rotation going of the different meals.
I think I'd do this if I weren't cooking for 4. As it is, I have salad for lunch every day and really only worry about dinner.
So a couple of hours on the weekend and you have many servings in the freezer ready to go:
Fish, broccoli, rice
Chicken, potatoes, green beans
Spaghetti and meatballs with sauteed mushrooms
etc.
You do have to use up some time and brain power to pick the 2 items to make each week, but then it's pretty effortless.
