You are absolutely spot-on correct with your Point #6. Processed Foods are the Enemy. You're in Santa Fe? There's a Wild Oats store there
http://www.wildoats.com/u/store176/ I do all our grocery shopping at Sun Harvest (part of the Wild Oats chain) and it completely transformed our diet. I'm not kidding. I was buying the same processed packaged manufactured "food" as everyone else, and feeling like crap. I began shopping there solely because of convenience (we moved and it is the closest store), and now I won't shop anywhere else.
Some thoughts... sorry for bloviating:
Sweet potatoes are delicious and nutritious, and I only discovered them last year. I like them boiled, then whipped with a touch of butter, honey, and orange juice.
I appluad you for avoiding chemical sweeteners. Stevia is a great alternative sweetener: natural, not chemical.
http://en.wikipedia.org/wiki/Stevia If roast turkey works for both of you, why limit it to once a year?
Stop eating in restaurants. If you do eat out, eat at small family-owned/operated restaurants. Most chains are now serving the same premade processed crap that we buy in the grocery stores. Their kitchen staff doesn't actually cook - they heat and serve. You're in Santa Fe, so you have a vast array of wonderful locally owned restaurants. Seek them.
Grilled cheese sandwiches! Grilled ham and cheese. Grilled turkey and cheese. Grilled turkey and cheese with avocado. Experiment with cheeses... mild or sharp cheddar? brie? smoked gouda? the choices are mouthwatering. Experiment with breads... whole wheat? sprouted grain? sourdough? texas toast?
BLT's are incredible with fresh locally grown tomatoes. The tasteless california crap isn't tomato, so don't put them on the table.
Reubens! Grilled pastrami with sauerkraut on rye and thousand island dressing! Ahhhhhh......
Ban velveeta and american cheese, and all their brethren. Do it.
While you're banning, ban crisco and other hydrogenated vegetable shortenings. If you must use a solid fat for a recipe, use butter, ghee, lard, or palm oil. Palm oil shortening and butter are great for pie crusts.
Get a crock pot and use it as a tool - not as a solution. My favorite crockpot meal right now is to throw in 1-2 pounds of country-style pork ribs set on low before I leave for work. When I come home, I pull the meat from the gristle, fat, and bone, drain the excess fat from the pot, then put the shredded meat back in with prepared bbq sauce. EASY bbq sandwiches for dinner!
I also will cook 4-5 chicken leg quarters in the crockpot (on low all day while I'm at work). The dark meat from leg quarters is wonderful in all kinds of dishes - especially chicken salads, stews, risotto, and soups.
Roasted chickens from the supermarket are a nice choice these days, but watch the salt. These are great shortcuts for recipes that call for cooked chicken, but you don't have the time to cook it yourself.
You say he loves soups but doesn't like most you've made. His tastes are likely corrupted by a lifetime of high sodium canned soups. He'll get over it if he wants to. Get a Costco membership and buy six packs of organic free-range chicken broth - this makes soupmaking much easier. Chicken stock, diced celery carrots and onion, split peas, and some cubed ham pieces makes a great and easy soup. Chicken stock, green lentils, diced celery carrots and onion and frozen spinach (plus a squeeze of lemon) is another good soup. He likes navy bean soup? Sneak in some vegetables like zucchini and yellow squash - just be sure to peel them (to hide the color) and dice them to navy bean size. Potato and corn chowder (chicken stock, potatoes, canned corn, celery onions carrot, and half & half) is a favorite of mine, especially with a butterpat floater sprinkled liberally with crispy bacon with a crusty chunk of sourdough for dipping. He likes it salty? Keep a salt shaker on the table and let him doctor his bowl to his tastes - he can't do worse than Campbell's. Get a salt grinder and use sea salt on table - it's more satisfying.
How committed is your husband to making dietary changes? He must find a way to eat his F&G, even if it means going to a smoothie or juice bar or taking superfoods supplements. He doesn't have to like his F&G, but he does have to eat them.
Don't forget breakfast. We used to skip eating altogether in the morning, then we began having buttered toast, then toast with jam, then we moved onto fried egg sandwiches, and our days have been wonderfully improved by this. One egg on two slices of whole wheat toast with a couple slices of canadian bacon is a protein-rich start to the day.
You didn't mention if either you or he smoke cigarettes, but if you do, I cannot stress strongly enough that your first and best choice should be to quit smoking. When I quit in 2003, I couldn't believe how much my taste buds woke up 3-4 months later. I was convinced that I was a culinary genius. Now I know - I'm not a genius, but I do have taste.
Keep it Simple. Not every meal has to have a main dish and two sides.
Remember - the more color you have on your plate, the more nutrition you have on your plate.
