For us, we have really had to change how we shop and eat to stay within our budget. Food prices have increased dramatically, we have a bigger family, and our little people are developing bigger appetites. We need more food, but want to stay with our old budget.
We buy bulk. I buy oatmeal, brown rice, beans, nuts, and flour in 20-50 pound bags. The cost per pound is very low.
We buy less fresh produce and rely more on our freezer. I bought a case of peaches last summer when they were cheap and we are still making smoothies. The same for blueberries.
We mix fresh milk with powdered milk to stretch it.
We eat one organic chicken a week. I stretch it over 3-4 meals. No other meat.
We skip most of the lovely treats we used to eat -- oysters, red meat, wine, olives, capers, delicious little things that can eat up the budget. Now we splurge on these things for birthdays and holidays.
We simplified out diet a lot. It makes cooking easier, costs loss and keeps our weight in check. We also live in the boonies and have little access to really good food. This is a big help. If I still lived in the city, I would be much more tempted to eat wonderful food. As it is, I have to be satisfied with wholesome food bought cheaply.
