Aldi's got whole cauliflower for $1.99 right now, and that's the cheapest you'll find it across the big four by a clear margin. Woolies is $2.25, Coles is $2.70, and IGA is sitting at $3.00, so if you're doing a mid-week run anyway, it's worth grabbing one while you're there. Cauliflower is one of those vegetables that earns its place in the trolley: roast it, mash it, throw it into a curry, or slice it up raw for the kids' lunchboxes. A whole head at two bucks is pretty hard to argue with.
