Get flour in bulk and a good sifter to make homemade bread (you can be assured it’s pat yisrael like that).
Chicken wings are often as cheap as 99 cents a pound. You can bread and fry them and put different sauces on them, like buffalo sauce or bbq sauce, for a cheap fleshig treat.
Soups are always a good idea- Osem bases, veggies, barley, beans are cheap.
I’ve had to cut back in recent weeks.
This shabbos, we ate out Friday night, but for Shabbos morning, we had homemade challah, tuna salad, and hamin made from beans, barley, potatoes, bbq sauce, ketchup, garlic, onions, oil, spices, and cut up franks and a package of cheap chulent meat. On the side, we had parve kishka (homemade and very cheap), homemade potato kugel (very cheap), salt and pepper kugel with fried onions, an apple kugel made cheaply, and some deli slices.
