What should you always have in the freezer? Rach shares her three favorite veggies to keep on hand: Peas for mashed potatoes and pastas, frozen corn for Tex-Mex dishes, and spinach.

"Frozen spinach? Biggest bargain in the grocery store if you ask me," she says. "It takes a lot of pounds of spinach to be one box of chopped frozen spinach, and I use that in stuffing, all kinds of things. Pasta dishes, even soups — just throw some in at the end and melt it into the pot."

And, make room in your freezer for bread crumbs and nuts to get the best value on those items. "If you keep them in the freezer you get your longest shelf life out of them," Rachael explains. "The bread crumbs won't go stale or get buggy on you and the nuts won't spoil."
