I'm in ca on the tofu/soy package
First off I've found it easiest to do all my WIC shopping at once and use the checks for the whole month.
I get the shelf stable soymilk (because out of the two options it 97% organic) and although I don't go through all of it every month, I just add it to my food storage and rotate through. I am going to start making soy yogurt which will use up a lot of it. But I also use it for shakes (with the frozen organic berries I buy using the produce check).
I get mostly frozen organic veggies and fruit from the produce checks so I don't have to worry about anything going bad, and its more expensive than getting fresh, which I buy with food stamps or out of my own budget.
I only get as much of the cold cereal (I go for the multigrain cheerios because it has the least amount of sugar and highest protein) as I will eat in a month opt to get the rest of the allowance in hot cereal (split between malto-meal and oatmeal). I eat those foods three times a week for breakfast and also for baking ruffians and cookies (recipes on the box). You can easily make your own granola from the oatmeal too.
I've started getting the concentrated frozen juices because I am bothered by not being able to find any WIC approved juices in glass or bpa free and that has helped so much with the storage issues. The frozen juices can also be scooped out a spoonful at a time and used as marinade bases and boost flavors in smoothies.
As for the dried beans, I really like making lentil loafs and bean burger patties. Both of which I can make in large batches and freeze for quick/easy re-heating later. I get the dried beans because of the BPA in canned foods and they do well in food storage as long as you rotate them.
I get a crapton of tofu, which I get both silken and (mostly) extra firm. I use the silken for pudding bases, Alton Brown's "Guilt-free Caesar" dressing with silken tofu, puréed as a flan, quiche filling or mousse and blend it up with marinara sauce for added protein. The firm stuff, I freeze first off the bat to improve the texture making it more meaty and then thaw as I need it. I make tofu scramble breakfasts on weekends, marinate it in strips and bake for dinners and sandwiches flavored a million ways. I'll cube it and add to soups, crumble it atop anything that I would use cheese like salads or casseroles. I'll also fry it up which isn't the healthiest but tastes so good.
If you get the dairy milk I would recommend making cheese with it. It's super easy and tastes so good. You'd need to also buy some heavy cream to add if the milk is non-fat and whatever herbs you want to favor the cheese with of which there are a million delicious combination.
As for the other stuff, eggs, peanut butter, ect. I use them up every month. I find that I having leftover tofu, cereals, and soymilk is useful in supplying my food storage in the event that I can't afford groceries in the future, and it feels good to be prepared. If I didn't want to do food storage I would trade with other families for things I would use (ie how 'bout some coffee and tp you buy in bulk for a few gallons of milk?) or donate what I won't use to the food bank.
