Onions have so many great health benefits including being full of antioxidants, they have anti-inflammatory properties, they have been shown to aid digestion, and are packed with vitamin C.
You can put these on your sandwiches, salads, tacos, or even pasta. These will stay fresh for 1-2 weeks in an air-tight container in the refrigerator.
Pickling food has been around since ancient times. It was an excellent form of food preservation before modern refrigeration was readily available. Luckily, pickling also adds an important flavor that has become a huge part of each and every culture around the world.
Pickled foods are readily available for purchase at your local grocery store and there are some fantastic products out there. I, however, love to experiment with different kinds of vinegar, herbs, and spices to see how they can transform a simple vegetable.
