With the cold weather look for stir fry veggies for a good buy at the moment. For Example consider capsicums, onions, carrots & brushed potatoes. All these lines are reasonably priced as alternatives to the dearer vege lines due to short supply.
Record cold temperatures along the eastern seaboard have seen the supply of many vegetables very short in supply thus sending prices upwards . If your looking for value veggies at the moment consider Asian vegetables such as baby bok choy or choy sum. Silverbeet and spinach still remain a reasonable buy!
