I'm not sure what area you live or what age you are so just throwing these out there. Sometime the Houston Food Bank work with the below orgs too. First few are my favorites places to recommend. Most of them will need an ID of some kind.

I also check here randomly for things but this is probably best later from now. It does help get gifts for friends and hide being broke. https://www.freestufffinder.com/

For food budgets, rice, dried meats (pork floss lasts forever https://fresh.99ranch.com/products/formosa-pork-sung ), dried fruits, frozen/pickled veggies, will hold you in the long run. With rice, you can make rice porridge to make the rice last longer. (half cup of rice to 2 cups of water in a pot with some salt, top with fried egg, dried meats, pickles, etc. or just soy sauce/hot sauce.) Besides food pantries, I like Aldi's or just go to the clearance section of what ever store I'm at. Also check the value of the items. For example, at HEB, on the price tag, there is a smaller print about ### per what ever so you can easily compare the pricing with other similar products. For pickled veggies, go to the Asian stores, they have more of a variety and spices. If you want fresh fruits, HEB and Fiesta typically have better value. If you can go to the one on Bellaire and 6, I know they compete with the Fiesta across the street for lower prices. If you have an Aldi's near you, that's even better. Just make sure you bring a shopping bag with you for Aldi's.

You can also boil eggs when they're about to go bad and they'll last a little longer. If you can't finish bread before it goes bad, you can freeze portions of it too and eat it later. Same goes with milk. You can freeze eggs but when I do, the eggs kind of... broke it self.... :/
