If you don't have any debt than most likely you can use your money to shore up any prep items that you need or to maintain a vehicle or a roof(you get the idea).
Five meals cost me under $2.00~ each week. Pictured below is a taco meal that is simple, but Bill loves.
Corn torts toasted on the comal- once they start toasting I fold them in the shape of a taco shell.
My older brother(when he lived nearby) saved his TV dinner tray's because I new the minute I saw them that I would use them to send meals to work for Bill. I have about 20 of them! I cook the beans weekly in the crock pot over night. I start them around ten and then by 6 am they are ready. In addition to serving them in any meals I send with Bill, we eat them through the week. The taco has cheddar cheese on the bottom, seasoned ground beef- the sides are beans and a jalapeno.
Then I stack the five meals and put them all inside a plastic grocery bag and freeze. In the morning I will grab one meal and send it with Bill. I also will send a homemade desert, water, tea or a fruit drink too.
Preparing meals in advance does take planning- in fact, I am browning some meat as I type this post for next weeks meals. But this time is well spent as you know what you are eating, and what hands touched your food. Please take the time to reduce the amount of time you spend on eating out, and put this surplus money towards storage.
