When looking to buy leeks at the grocery store and introduce them into your life look for firm stalks and leaves.
To prep, discared the outer green leaves and cut lengthwise. Soak in cold water until all the dirt is gone, then drain. Saute with other veggies in olive oil for a side dish, or slice and use in place of onions for a sweeter, milder taste in soups and salads.
Simple and super healthy!! Enjoy!
