Chop one head of romaine or dark leaf lettuce. Slice 1/2 a cucumber and a few radishes, cut a red or green pepper into strips, throw in a few tomato slices and toss in chunks of your favorite cheese or plain nuts (a more eco-friendly choice). Top with the dressing of your choice. If you like, you can add slices of grilled chicken breast or boiled eggs that you have on hand. Leftover grass-fed steak pieces work great, too.
