Anyone you can borrow money from at all? Advance on pay?
Call a local church and they will give you a box of food, even if you don’t attend their parish.
Food pantry, ask local Facebook groups
Yes I was gonna suggest a food bank! Also pasta! It’s about 1-3 dollars per pack of pasta and same for sauce!! Easiest and cheapest!
Local libraries often have child snacks they put out, or join your local Facebook buy nothing group, there’s always people in mine who are giving away stuff including food! You just have to be quick to be the first person to comment or go pick it up. I would also try a local church or even YMCA, they’re often food bank distributors and I know my YMCA often has food for free people bring in
Do they do the free fruit baskets where you're at? Like at Woolworths here, they have a basket of fruit for kids while they walk around shopping. Do they have those where you are?
