I don't think eating healthy is very expensive. I don't coupon as much anymore because I cannot eat many foods that coupons are for. My diet is strictly meats, some dairy and produce. Maybe 5% grain based foods. Nothing pre-made from a box or freezer. I have a local grocery store (Goodness Me) that has lots of great sales on Organic Produce. Fortinos does as well. The only bread I normally eat is bread I make myself (Water, flour, salt, sugar, yeast-pretty easy)
We get all our meat from costco. We buy Beef, Chicken, Salmon, Rainbow Trout and usually something different to change it up (Different kind of fish, veal, pork, whatever) We spend around $100 just on meat. We cut it up into portions, vac seal it and that is enough meat for us for a few months. The other night I made a whole roasted chicken for dinner which was $5 at Fortinos which had enough left overs for my husband to make wraps the following day. Our side was $0.75 worth of broccoli and carrots. The night before that we had rainbow trout baked in the oven and peas/corn as a side. I don't know what exactly the trout cost. I think a tray costing $17-$19 comes with 6 very large fillets, enough to feed two people. Organic frozen peas and corn were about $2.99 a package and I only used about a handful of each, I can't really put a price on that but I hardly put a dent in the bag.
A bag of organic apples is usually $3.99-$4.99, it usually lasts us 2-3 weeks. $2 worth of bananas ($0.70-$0.90/lb for Organic) lasts a week more or less depending on how many are in the bunch. I don't buy ALL organic (I cannot afford meat or dairy). But produce is normally pretty inexpensive regardless of what you're getting. Tomorrow I'm making cauliflower soup and I'm throwing in a chicken breast and a pork chop and adding carrots, onions and Hungarian dumplings. It's pretty much pennies a serving as it normally last several days afterwards from just 1 cauliflower and it's traditionally made with leftover meat but we want to clear out the freezer lol I also have a dumpling recipe you make out of stale bread.
I personally drink lots of coffee, tea and water. Try having a large herbal tea or glass of water before dinner, it'll normally keep you full all night. I do drink some orange juice but water it down 30% so it lasts me over a week.
This spring/summer we plan on doing a lot more hunting and fishing, thus providing us with lots of healthy food essentially for free from mother nature. It couldn't get much cheaper than that.
