Start with a big head of cauliflower and cut it into four pieces. Slice the core out, on a diagonal. Make slices, then dices. You don’t have to make perfect florets and don’t throw away any pieces that seem like mostly stem. That’s just as delicious when you roast it.
Pile cauliflower on a baking sheet and slather with extra virgin olive oil. Sprinkle with salt and mix it with your hands. Spread out evenly on the pan.
Into the oven for 25 minutes, flipping once halfway through. If you get the edges crispy and the insides still soft, you won’t have even one bite left.
