Just made a very weird treat that was way too good:
Cauliflower Popcorn: Take a head of cauliflower and cut it into florets, toss with 1/4 cup olive oil and 1 tablespoon salt. Roast in the oven at 425 for 1 hour, stirring every 15 minutes. (Mine cooked much faster because the head was smaller.) Remove when brown. Eat immediately.
It really looks and tastes a little like popcorn.
