Tip 1: Skip the prepackaged salad mix.
Sure, bagged salad mixes are convenient. And anything that makes it easier to eat your veggies is a good thing. But they’re also expensive and can quickly go from perky to wilted to downright slimy. So try buying heads of lettuce (which often last longer in your crisper) and make your own mixes. Try mixing up romaine, radicchio, red leaf and/or escarole.
