Good thread, but I think your prices are low for most areas of the US. Good luck getting blueberries for 1.99/pint in most places.
And I think you need more protein in your diet. Chicken is relatively cheap....especially when purchased frozen and in bulk.
I just bought 20 pints of fresh blueberries on sale at Kroger last week for 1.49 a pint. Divided them up in freezer bags of 4lbs a bag. I go through a 4lb bag a month.
This is the easiest time of the year to eat good. Been doing tons of grilled veggies like zucchini this summer.
Blueberries dropped to $0.99 at Aldi last week here. I bought a couple dozen and have them in my garage freezer.Our monthly food budget is a variable $700 for my wife, a 4 year old, 2 year old, and I. I used to personal train, and still work with a few people, that pay cash only. We add whatever I make to the food budget. Start every month with $500 then add part of my personal training earnings.
Breakfast - oatmeal, banana, bagel. I can find each of those components for less than $0.15 per. Costco, Aldi, and Entemann's outlet respectively.
Pre workout - Spinach. We try to buy spinach when it's bogo ($2 per bag) and freeze one. Each lasts more than a week usually.
Post workout - Protein shake. Used to make my own, but now that I workout over lunch that doesn't work. The Costco stuff is like $1.25 per, but I've gotten it on sale for < $1 per before.
Lunch - sandwich (usually turkey or tuna), veggies + hummus. Veggie is usually cucumber or celery. Two cucumbers and a bundle of celery runs me about $2 at Aldi and it lasts a week. I always add spinach, tomato, and some kind of onion to my sandwich, regardless of what it is. Turkey is $2.99/pound at the deli and a 1/2 lb lasts me a week. Tuna varies, but can usually find it for < $1 per. We grow our own tomatoes (cheap!), but there's probably a more cost effective way for us to get onions. I usually just buy one ($1+) whenever we run out of one. Definitely is with hummus, but $6 at Costco for a tub that lasts me a month? That's fine. Because of the Entemann's outlet all of our bread is a $1 per, try to buy the good stuff right after it goes on the shelf then freeze for later use. Get a freebie with each purchase too and they usually have something we plan to use anyway.
Afternoon snack - cottage cheese, fruit. Right now fruit is blueberries because of the above. Tub of cottage cheese is like $6 at Costco, lasts me a couple weeks.
Haven't ever figured out exact cost of everything I eat during the work day, but it's probably less than whatever my co-workers spend on lunch. My wife is not as cost conscious with her at-work food budget, but she's pretty good too. She eats a few more grab and go things like nutrigrain bars and trail mix.
We spend our savings on alcohol and good meat and we try to end each month in the black by $100, so we can go out for a nice meal.
