What is the best way to buy lettuce? Don't buy iceberg....period!
Iceberg has VERY little health value. Buy spinach or a spring mix instead. Even Romain would be better.
We generally use spinach for salad, sandwiches, casseroles and pretty much anything else we can put it in.
If you have a hard time swallowing darker leafy greens, buy the iceberg and then cut the spinach into small shreds and add it in.
Here is a website I found that backs my theory....I love it when that happens :).
