No, you should not put frozen vegetables in the fridge. Frozen vegetables should be stored in the freezer at all times until you're ready to use them. Freezing helps preserve their quality and nutritional value, and putting them in the fridge would cause them to thaw, leading to potential spoilage and a loss of texture and taste.
When you're ready to use frozen vegetables, take out the amount you need from the freezer and cook them immediately. If there are any leftovers after cooking, it's essential to store them in the refrigerator and consume them within a few days. However, you should never return thawed or cooked vegetables back to the freezer, as this can lead to food safety issues and affect the taste and texture of the vegetables.
