I don't think it's possible to buy frozen raw veg around here; it's all blanched to avoid it losing color and getting slimy when thawed. Don't like frozen spinach but it does take up a lot less space in the fridgeAccording to the packages I buy 12 ounces (340 grams) of broccoli/cauliflower is 80 calories, 12 ounces of spinach is 120 calories, both frozen raw, pre-cooking.
