We plan for the week (two adults, one toddler) and do our shopping over the weekend. On Sunday mid-day, we make a big egg, zucchini and sausage frittata and a huge batch of turkey and sweet potato hash. These two dishes become our post-work-out meal and breakfast (we both work out in the early morning, have some hash immediately after the workout, and then a slice of the frittata about an hour later). Lunch is always a BA Salad - lettuce, mixed chopped veg (from Trader Joe's -- comes pre-chopped), a pre-cooked chicken breast (also from TJ's), olives, mushrooms, cherry tomatoes, avocado, pine nuts, and homemade dressing or just some oil and vinegar. Those things are pretty much the same every day, pretty much every week. There's the occasional other egg dish on a weekend or what have you, but that is really about 90% of our breakfasts and lunches. Since we eat it week after week, it makes shopping easy too - no new planning.
We have more variety in our dinners, but pretty much every week involves:
1 large roast (either a pork roast or a whole organic chicken, usually in the slow cooker on sunday) with tons of roasted veg. Tonight was chicken + butternut squash and broccoli. It's enough to last another night, possibly 2 more nights.
On Tuesday, I'll make a huge pot of beef chili - 2 lbs organic grass-fed beef (trader joe's again), 1 onion, 5 organic bell peppers, three cans of tomatoes with green chiles (TJ's tomatoes are all canned BPA-free, just FYI), one can tomato paste, spices. We'll serve it over leafy greens (like kale or spinach) or do a side of some other veg. That should last 2-3 nights, depending on how much veg we have. One favorite is to do the fake cous-cous (from cauliflower) from the Well Fed cookbook/Clothes Make the Girl blog.
On Thurs or Friday, when the rest of that food is gone, we'll make a stir fry (frozen shrimp, frozen veggies, homemade stir-fry sauce) or sometimes just order sushi/sashimi in if we are too tired.
And many, if not most, nights, I like a an apple sliced up with almond butter on it (raw, unsalted, from TJ's)
For the most part, our daughter eats what we eat. She still does some dairy - whole organic milk, and some organic cheese and butter, but otherwise she's a protein + veggie + fruit girl.
We don't have time to vary our menu all that much. I personally don't get bored with it, my wife has more desire for variety, but we try and strike a balance between keeping things interesting and keeping things simple.
