Breakfast is usually egg custard with fruit or egg muffins with meat and veggies around here. So we each get 2 eggs/day just from breakfast. Most days that's all the eggs we get. Although I don't have a problem with eating more of them... they are a cheap source of protein.
Leftovers usually make up lunch. Whether it's from the night before or whether I cook a big batch of something early in the week. In addition to leftovers, DH's lunch bag might have (homemade) yogurt with berries, veggie sticks, dip, fruit (grapes, bananas, apple, orange, whatever's in season), nuts, string cheese, depending on what I've made that week. If I've made almond bread, cookies or cake, he'll usually have some of that in there too.
Dinner is meat and veggie. Hamburger patties with all the fixings (lots of lettuce, tomato, onion, pickles, bacon, cheese) makes a nice dinner. Chicken or pork curry (with whatever veggies I have on hand). Occasionally it'll be leg of lamb with mashed cauliflower, or steaks with sauteed mushrooms and a green salad. Sometimes it's a stir-fry of meat and veggies, or I make meatloaf, or meatballs and spaghetti squash, or almond crust pizza. If I'm feeling particularly lazy, I'll make a moussaka early in the week and we'll have that a couple nights. If I don't feel like cooking, it might be a large salad, taco salad, duck salad, tropical chicken salad, BLT salad.
Snacks depend on what I could find at the market, what I was craving and how much energy I had for cooking that week... sometimes it's just nuts and veggie sticks, sometimes deviled eggs, sometimes it's meat rolls (thin sliced meat, usually leftovers, wrapped around a piece of cheese or veggie). I also always keep fruit in the house to snack on.
As for affording it, it's no more expensive than buying packaged food around here, and we live in one of the highest cost of living areas of the country. It does mean I can't do all my shopping at a big supermarket, as our supermarkets have crap for selection. I buy everything I can at the farmer's market, then Trader Joes and only then do I go to the supermarket if there's anything left on my list, once a week. I buy everything I can in bulk (beans, herbs, spices, rapadura, honey, etc.) at the local HFS every other month or so. I shop Target 3 or 4 times a year for non-food stuff (toiletries, toilet paper, tylenol, etc.). And the key for me is not stopping at the store to pick up one thing in between trips. If I forgot something, I rearrange my plans rather than making another trip to the market. I discovered I cut my spending a LOT when I cut out those extra trips for "just one thing" that always turned into $20 or $30 trips.
This does require a change in your thinking patterns. And it requires a bit of planning. I found that for most people, planning out meals and snacks for 2 weeks really helped get them over that hump. After those 2 weeks it became easier.
