Trim the head of cauliflower, discarding the core and thick stems; cut florets into pieces about the size of ping-pong balls.
In a large bowl, combine the olive oil and salt, whisk, then add the cauliflower pieces and toss thoroughly.
Line a baking sheet with parchment for easy cleanup (you can skip that, if you don't have any) then spread the cauliflower pieces on the sheet and roast for 1 hour, turning 3 or 4 times, until most of each piece has turned golden brown.
(The browner the cauliflower pieces turn, the more caramelization occurs and the sweeter they'll taste).
Serve immediately and enjoy!
Where I got it: I originally heard about this recipe at Gail's Recipe Swap, where Josh posted it and many folks tried and loved it.
