I'd like to see that too. It's probably terrible. My wife and I probably spend $600 every 5-6 weeks and it's just the two of us, no kids. And we bulk shop (Sam's Club) so it's cheaper. Back when we went to the supermarket it was like $500 every 2-3 weeks.
We both have health conditions, so we don't do takeout, do all our own cooking to account for our needs. Our bill is probably a bit higher do to that, but it mostly involves avoiding salt and sugar and eating healthy as possible.
Same, we're not buying anything fancy. Bulk meats, some fresh fruit and vegetables, and we buy a lot of dry and powdered goods that keep (wheat gluten, pastas, beans, etc.). Milk, sour cream, eggs, butter, orange juice, some bread. We get some snacks here and there, but minimally and generally it's stuff that can be added to make meals anyway, like tortilla chips and the like, or dips that can be thinned to make convenient sauces.
We even make our own treats, like I make my own yogurt and peanut butter from starter and whole peanuts and cashews, and my wife makes homemade ice cream sometimes.
