Roasted Cauliflower With Onions and Fennel

From the March 2007 Gourmet magazine, to which I have subscribed for more than 35 years. This combination is outstanding and the prebrowning of each vegetable is key. (Yes, it's more work, but it is worth it!) It is delicous hot and even better at room temperature.

Ingredients

• 1 (1 1/4lb)  cauliflower, cored, cut into 1-inch florets
