I don't have the info you're looking for.  It wasn't easy to find when tried -- and as you've figured out.  But I do have a slick spreadsheet that I put together for determining what I was putting in a meal in terms of calories, carbs, proteins, and fats -- and it could be extended to include vitamins and minerals if you had that info.  In my world, EVERYTHING goes in a spreadsheet -- and the more tabs, clearly, the better! 

Tabs:

• Milo's weight, age, activity levels, etc and the formula for how many calories he needed, with a scale factor for adding/losing weight.  This is where that info you're looking for would be added -- what are the vitamin and mineral needs, in addition to calories and fats, carbs, proteins.
• Various foods and their nutritional info per unit, e.g., 1 lb chicken breasts is 20g fat, 35g protein, 105 calories (making this up for the post!), 1 can sardines is 40g fat, 40g protein, 75 calories.  Every time I added a new food to his diet, I'd add a newline to this tab.  A few more columns would cover the vitamins and minerals.
• "The Mixture" page, which had a pull down menu to pick from the "Various foods" page.  I'd select the food type and the amount I had (1.2 lb chicken breast, 0.80 lb ground beef, 1 lb broccoli, etc)  The scaling and summing happened automatically.  At the bottom was a highlighted total with Total calories, protein, fat, carbs, and a place for how much "Mixture" resulted, e.g., all the mixed stuff resulted in 12 cups of food.
• "The Feeding Page" combined all of the other info (Milo's calorie needs, mixture calorie info, and mixture quantity) to tell me how much to feed him on any given day.  It also output the daily protein, fat, and carb info so I could be sure I was in the recommended ballpark. (For example, if a mixture used ground beef, it had higher calorie than if the same amount of chicken, but if I had used 5 different vegies instead of just 3, then the volume would be lower calories/cup -- you can't just assume a cup of "mixture" is the same from batch to batch -- this page figured that out for me.) 

By using the spreadsheet, I could cook up a storm on Sunday using the food processor and whatever I had in the frig and had found on sale at the grocery, and have food for the rest of the week.  In addition to the food mixture, he had a daily vitamin and calcium supplement, and then a few other herbal and cancer specific supplements and K-9 Immunity .

The spreadsheet I put together would work for you -- IF you could figure out what the nutritional needs are for the various vitamins and minerals (I never found it), PLUS extending the "Various Foods" tab to include that vitamin and mineral info for all the food types you throw into a mix.  The spreadsheet format is easy, just add columns, but getting the vitamin and mineral info for some foods may be tough. 

Anyway, if you ever start to gather that info, and are interested in what I have, let me know.  I haven't used it since October (sigh...), but I'm sure it's still around.  I rarely delete my cool spreadsheets!

Will find this weekend, add comments, and post somewhere.  Got a high pressure work project tonight, though.  Hopefully, it helps you and others.

Here's a link to the spreadsheet on Google Docs.  I think I set it up right for sharing for all.  Let me know if there's a problem.  I added a few comments to help explain it.

Best of luck.
