Sweet Onion Salad is a crisp, refreshing side dish featuring thinly sliced sweet onions (like Vidalia or Walla Walla) as the star, often tossed with a bright vinaigrette, fresh herbs, and sometimes a touch of sweetness. It's a staple at summer barbecues and picnics across the United States, particularly in the South and Midwest where these sweet onion varieties are grown.
This salad is low in calories (around 50-80 per serving) and provides a good source of vitamin C and antioxidants from the onions, with minimal fat or protein unless added ingredients like cheese or nuts are included. Its primary nutritional value comes from the onions' fiber and beneficial plant compounds.
