Get a Deep Freezer (If You Have the Space For It)
Reddit user omegaphora says:
"That thing has been incredible. Budgets ebb and flow. In lean times, it has been great comfort to me knowing that I have "fresh" fruits/veggies in the freezer, for all sorts of uses. Dry goods/pantry items alone get very tiring and redundant. We have at least a few months of food now in the fridge/freezer, deep freezer, and pantry.
"Our tactic now is to buy in bulk and buy on sale. Many fresh foods can be frozen on a cookie sheet, then transferred into a container (diced fruit for smoothies, diced veggies for soups). I usually bake two loaves of bread at a time — freezing the extra one."
