Salad kits
Washed and bagged greens can be a time-saver, but they can cost three times as much as buying a head of lettuce. Even more expensive are salad “kits,” where you get some greens, a small bag of dressing, and a small bag of croutons. Make your own croutons by toasting cut-up stale bread you would otherwise toss and try mixing your own dressing.
