My mother has always been the thriftiest person . She grew up in the projects with only her mom and 4 children..They were never on public assistance, so they learned to be very thrity.
In her home and ours growing up..
No real snacks like chips.. But lots of popping our own popcorn..
No sodas but we could make iced tea and lightly sweeten it.
They ate beans of some sort at least 5 days a week. Then they turned it into soup and then bean dip sometimes. Black eyed peas, pintos, Lima, split pea.
Since my grandmother knew how to make homemade tortillas.. they ate the flour or corn tortillas instead of bread..
Lots of rice, all kinds and all ways.. chicken and rice, chicken with canned tuna and creamed soups. Arroz con pollo. again leftovers became soup by adding broth and veggies.. Rice pudding was a treat as a dessert.. if rice was on sale for a super good price.
Milk is a necessity, so you just have to look for the best prices.
Cheese was considered a luxury, so they only purchased when on sale and froze it.
Cereal we were not allowed sugar cereal because t was too expensive. So Cheerios, chex, corn flakes and raisin bran were a staple for breakfast and could be dinner or snack, so we kept a lot of it around. If the prices went way up, we ate eggs for breakfast with tortillas.
Today at the store they had 10 lb bags of potatoes for $1.99.. that would mean lots of potatoes all different ways. (my mother would have purchase 20 lbs worth.. Baked topped with whatever we had.twice baked. mashed potatoes, with left overs potato pancakes.skillet potatoes..
Breakfast tacos with skillet potatoes and eggs on tortillas and hot sauce made with canned house brand tomatoes, onion and chopped jalapenos.. this could be breakfast or dinner.
We never could afford breakfast meats unless it was in the mark down bin.. I pick it up for about 99 cents when I see it. I purchase a few chubs and freeze it for special weekend breakfasts.
Canned biscuits on sale for less than a dollar a can again can be with a meal, be the meal at breakfast or can be a treat with honey and butter..
We never purchased pancake mix, instead my mom made up a container of the dry mix in a large container with instructions on adding the milk and eggs.. Dinner, breakfast or a treat..
Fresh fruit that is on sale.. Apples and oranges mainly.. To make it a little more exciting she would purchase a few handfuls of grapes, a couple of bananas and a can pf chunk pineapple and make up a tub of fruit salad.. we ate this as a salad or breakfast or as a treat..
She would study the sales each Wed to decide what out meals would be. She purchased large quantity of things like asst pork chops, brought them home and broke them down into portions for a meal.. Whole chickens on sale for less that 99 cents a lb, she purchases and freezes as many as she can fit in the freezer.. BBQ, roasted, boiled ...
Ground beef the and Roasts the same.. When on sale purchase for an amazing price and freeze it..
This is how I was raised and pretty much keep our food prices down..
