Fresh sweet onions from the American Southwest, packaged in a convenient 5-pound (2.27 kg) bag. Southwest sweet onions are prized for their mild, sweet flavor and notably lower sulfur content compared to standard onions, resulting in less pungency and a pleasant natural sweetness whether eaten raw or cooked.
These onions are naturally fat-free, cholesterol-free, and low in sodium. They are a good source of vitamin C, folate, chromium, and prebiotic dietary fiber, which supports healthy gut bacteria and digestive function. Sweet onions are rich in the antioxidants quercetin and allicin, compounds associated with immune support and anti-inflammatory benefits.
Southwest sweet onions are exceptionally versatile in the kitchen—ideal for fresh salsas, salads, sandwiches, French onion soup, caramelized onion dishes, grilling, and fajitas. Their natural sweetness intensifies when cooked, making them a favorite for any recipe calling for a mild, flavorful onion.
