What advantage do large bags of frozen mixed vegetables offer over out-of-season fresh produce for budget shopping?

They are typically picked and frozen at peak ripeness, preserving nutrients

Frozen mixed vegetables are a highly effective strategy for adding essential nutrients and texture to meals without substantially increasing the budget or relying on expensive fresh options. The key advantage is that these vegetables are generally harvested precisely when they reach their optimal ripeness level and are immediately flash-frozen. This rapid freezing process locks in the vitamins and nutrients, often preserving them better than fresh produce that must endure long transit times or sits waiting for purchase out of its natural season. This results in a product that is both cost-effective per pound and nutritionally dense.
