What a cute site!! I just got through the "why I do this" page and had a major Awwww moment. Too bad he isn't interested in changing his ways but rock on for supporting her. J is the same way, he's not going to change... but what he doesn't realize is that he's changed a lot since being with me. Every little bit helps
I can't really get a sense for what you're looking for. I do understand the position your in though. It's tough sometimes. We grocery shop together. That way I see what he really wants to eat (and sometimes secretly put it back hehehe) and I can get creative around that. I do all the cooking so that helps me too. Trying to do all this on the cheap sometimes has it's limits though. Buying food and wasting it is a huge budget killer, so here's some further suggestions:
Make a "meal" list. Don't think of it as, "oh we're out of green beans better get some more", try and think of it in terms of meals you can make and how much you need to buy to do that. I'm waaay too lazy to fully meal plan out a week but I generally buy stuff that are parts of meals and then I buy stuff I can make big batches of and eat at least twice. Whatever the case, I look at the grocery list, or glance in the cart, and see if there is too much of something and if I can buy something to use it up and complete a meal.
Try and adjust the budget so you can spend what you want on food. This was a tough one for me. But really, if you can't spend money on food, the thing that keeps you going and provides your nutrients, then what are you spending money on.... for me it was soy lattes at starbucks which they always burned the soy and I gave up trying anyway.
Figure out what you both like, and also what you do not like. J hates rasins. Hates em. I love them on salads, in bannana bread but I just get over it and eat them when I'm out. Grocery shop accordingly.
Make a pantry list. Things you need on hand to make other things. I need at least 4 different kinds of vinegar, 3 mustards, 2 kinds of rice, sauces etc. I always have tofu, cans of beans, though I like to make them fresh, pasta of all shapes and kinds, fresh garlic, lots of seasonings. vegetable stock is super handy, as are canned tomatoes, artichoke hearts, miso paste, slaw mix, egg roll wrappers, and burritos. In the freezer, keep veggies, like brocolli, mixed pepper strips, spinach, green beans, and homemade lettuce wrap fillings around for easy meals.
Wow I'm hungry now but I just ate! With all that stuff on hand I can make at least 15 different meals that we both like. Tonight I made a "Just like honey" and lemon pasta with mixed pepper strips, broccoli and lemon pepper tofu. It was freakin awesome... and easy and cheap. I made two batches, one for dinner tonight for me and him (he works all night tonight so he'll eat there) and he, of course, grabbed a can of tuna to top off his. It will also make a wonderful cold dish for tomorrow's lunch.
Phew- sorry that got so long! I hope that helped at least a little
