I believe the best thing to do is to find out what you really need. Get the things that are necessities and avoid a lot of perishable food, which might not sustain you for long being fresh. Write down all that you need and tick what is urgently needed.
Get something you can eat alot of. Make spaghetti and eat on it for 3 days. Along with that get some ramen noodles, hot dogs, bread, peanut butter and cheese. That way for 3 days you've got the spaghetti and then the rest of the time you can eat pb sandwiches, grilled cheese, and hot dogs. You can even get some mac n cheese to go with your hot dogs or maybe some canned tomato soup for your grilled cheese. It may not be gourmet but it will keep you from going hungry. I'm in the same exact boat with 2 kids and my husband. I don't know what were gonna do for the next 3 days (I've got NOTHING) but you've got options! Hope it all works out for you. =)
This a problem faced unfortunately by many. First, simplify the problem: $16. for 6 days averages to $2.50 /day. Sit down and figure out what you can buy for two or three meals a day; consider preparing some meals like spaghetti that can last more than one day. You can do this. It happens that sometimes we have to eat what we don't want. This is your opportunity to do the hard! GOOD LUCK
buy eggs for sure, you can do so many thinks with eggs. Pancakes mix also goes far. Get lunch meat (Ham) you can chop it up and put it in your eggs w/ cheese. Bread is always a staple. Good Luck. I do it every week, so I know ur pain:-(
You should see if there is any local food box distribution. In my area there are a couple of churches and the local access pantry. Beans and rice are a complete protein. They are inexpensive when bought in bulk. An onion and a can of tomato paste in the beans. Some local animal shelters may have help for your dog. Good luck.
