Green onions, or scallions, have a mild onion flavor and long hollow green leaves.
They are fantastic as a flavorful garnish, used in dips, or in egg dishes.
Wrap your green onions in a slightly damp paper towel. Then, place them inside a plastic bag or storage container, this should keep them fresh for a few days. Another option is to place your green onions in a jar cover the roots with water. Then, place the jar on the windowsill in your kitchen. Your onions will stay fresh, and continue to grow.
