For weekday breakfasts, we alternate between oatmeal, eggs and salsa in corn tortillas, eggs/toast/potato combinations, and whole-grain french toast with mixed berries. For lunches, I only try to make sandwiches a couple of times a week, so the other days, we have leftover rice or soup from the previous night's dinner, or a simple stir-fry, or quesadillas.
We do have some favorite recipes that we cycle through, but I love to cook new things, so we usually have a couple of new dishes every week. And as a general rule, we don't eat dairy and meat in the same meal, so we'll have cheese and sour cream with our bean dishes, but will stick with veggies and grains to round out our meat meals. It keeps things relatively simple.
