I'll ask again, can you show me what a $10.71 day looks like?
Breakfast: What are we having?
Lunch: What are we having?
Dinner: What are we having?
Snacks: What are we having?
Assuming we are only drinking water.
Breakfast: I'll usually make eggs, pronghorn breakfast sausage, and pancakes (or biscuits to go with sausage gravy) on the weekend that lasts us through Tuesday or Wednesday. During the week it's yogurt with granola and fruit and maybe a hard-boiled egg if I'm headed out the door quick. Half the time, I'm working from home, and those days it's usually 2-3 scrambled eggs on a toasted bagel w/ cream cheese.
Lunch: I never cook lunch, so it's always leftovers from dinner.
Dinner: This meal varies the most for us by far, some staples that seem to get cooked every couple weeks are spaghetti with mule deer meatballs and one green veggie (broccoli or asparagus usually), some asian style wild game meatballs with roasted veggies over steamed rice. We do more grilled cheeseburgers (with a veggie and pasta side) and steak kabobs grilled in the summer months when the weather is nice, more roasts/stews/shredded meat type dishes in the winter months. We throw in a mexican dish every couple weeks too either fajitas, tacos, or smothered enchiladas.
Snacks: I need to cut back more in this area but it's tough right now with a toddler, so I promise my family is on the extreme side of snacks available right now. Cereal, goldfish, granola bars, string cheese, yogurt cups, fruit pouches, enough berries and fruit to feed a small army are always stocked in our pantry and fridge right now.
Drinking: Correct, we drink no sodas, but occasionally buy juice for the aforementioned toddler, along with a ridiculous amount of milk. We do have a $30/mo bougie coffee subscription that didn't look like it fell into my grocery spending, but that doesn't move the needle much.
I really thought I was being fairly generous with a monthly grocery bill of $300/pp, so I'm surprised this one is drawing scrutiny. It's not a budget where you'll be eating a 20 oz grass-fed bison ribeye three times a day, but I don't think that's fair as an average example either. For a family of 4 that is a $1200/mo grocery budget which seems like it would cover the hungriest teenagers I know.

@maxx075 posted above, buying bulk ramen or rice and beans could cut this down to like $2/day in a real survival-budget scenario.
