@jazmina88, ok, some limitations there if your budget is that small. I understand completely, since I have financial troubles myself. I think it sounds like your biggest problem is having to rely on what the food bank gives you, which is going to be cheap white rice, pasta, etc., which isn’t good for your diet.
White rice is generally not a good idea for diabetics, but if you have tested it and it works for your diet, a rice cooker is a good way to cook a batch of rice, then store the leftovers for future meals and that reduces your cooking time overall. Pasta also isn’t good, too, but if you have to have it, test it first. If it works, then follow the exact serving size.
If you’re eating grains, best to do brown rice, quinoa, bulgur, and barley. Pearl barley is especially easy on your sugars. Unfortunately, except for brown rice, these tend to be expensive, especially if you buy them from the grocery store or health food store. You may want to try to buy them in bulk; it’s cheaper that way.
@DigitalBlue is correct that canned veggies will last longer. Fresh is better for you, diabetic or not, but canned will do. Beans, as several suggested, are good, but just limit the serving size. Lentils are the best, nutritionally, but most legumes/pulses should be fine.
@augustlan, peanut butter is fine, from what I understand, but probably best to buy a brand with the lowest possible amount of sugar in it. Unfortunately, low-sugar/“diabetic friendly” foods tend to be more expensive than their cheap corporate products, or the store’s generic offerings.
As for recipes, buy whole chickens (or frozen) as @DigitalBlue suggests; much cheaper (they didn’t even sell chicken pieces separately at the store on a regular basis until about 35–40 years ago; everyone bought whole chickens or had the butcher cut off what they wanted/needed. Now we have all these pre-packaged separate portions of thighs, breasts, legs, etc., and they’re as much or almost as much as buying a whole chicken! sheesh…), and you can bake/roast it on the weekend, then carve it and save slices/pieces for the workweek to use as main dishes/elements in soups, salads, etc.
Eggs are excellent, diet-wise, so include them, if you haven’t already.
For recipes, hard to say. Diabetes is an individual disease. What affects one person may not affect another. Figure out what you can handle, then work with that. Generally, for you and your budget and schedule, I suggest soups, salads, chili, frittata, and other similar meals that you can make once, portion out, and then keep refrigerated/frozen (chili freezes well; just don’t leave in there for months!) until you need to use it.
Good luck!
