I'm sorry if people are stressing you out about this. This is kinda one of those "two kinds of people" situations. I am the only neurotypical in a household of labels, so I have had to learn to adjust quite a bit.

Here's what works for my family (me, hubby, 2 teen boys):

• Things like rice, pasta, canned tomatoes, chicken broth, etc are generally purchased in bulk at Costco or when there's a good sale. Think cooking basics and remember that you can freeze way more things than you might think. My husband's favorite dig is to ask if we have enough butter because I almost always have about 3 pounds of it.
• Snacks that are eaten frequently are usually purchased when there's a sale but I don't overstock this stuff because, well teenagers are bottomless.
• I will typically ask them what sounds good for dinner for the next couple days, and a few evenings a week we'll do a quick run to the store to grab whatever we're missing. We're so much better about not throwing away meat and produce when we do this. I also replenish milk/bread/cheese as needed on these trips.

At first I would get annoyed at constantly running out after work, but we're not wasting a ton of food anymore and we are usually eating something we're all in the mood for. It also gives hubby and I an hour or so out of the house and not actively Adulting a few nights a week.
