Search for food banks in your area. There are three in my town and one gets really good product from some of the nicer stores in town. They give us two grocery bags to fill, then usually have two more bags filled with pasta or soup mixes. And that doesn't account for the fresh produce they provide. I've filled my, my sister's, and my mom's pantries from a single visit to the food bank. I never felt like I was taking too much, but I always end up with more than one man can eat on his own. So, my sister gets to feed her kids and my mom can feed the ladies that help her at home. Their hours may conflict with your work schedule, but a single trip can benefit you immensely. Maybe get a friend to go if it doesn't work out timing wise for you.
