Very relatable! I might steal that hummus idea as I looooove hummus.
I pretty much eat the same thing every day and it looks like this:
Oatmeal, almond milk (lasts longer), banana
Natural peanut butter
2 hard boiled eggs
Salad (romaine lettuce, carrots, cherry tomatoes, dressing)
Wrap (tortilla, mayo, shredded cheese, and some kind of meat from the freezer)
I put together an Excel workbook where on one sheet I enter servings per container, cost per container, and how many serving I eat. Then on another sheet, I can put in what foods I ate that day to get a total cost for that day.
The above comes about to about $2/day.
Then I go to the local Amish market and get a single meal (snack really) for ~$7 (3.5 days worth of meals).
...no regrets!
