Star # 2 Take the romaine lettuce you are using or any other leafy veg. and cut it into pieces. Discard any bad parts. Thoroughly wash it.
Toss the romaine In a salad spinner and dry them really well. If you don't have a salad spinner get one it is cheap. For the moment just dry them very well with paper towels.
When the romaine is dry stuff It in a jar and cover it with a lid. You can fit a lot in a quart size jar it's amazing. That's all easy does it.
Ahh now I have salad on the go whenever I want. Enjoy
The greens stay fresh and crisp for about a week maybe more. Try this method with spinach, kale, Swiss chard, iceberg lettuce etc. You will not be disappointed I can assure you of that. :)
