Line a baking sheet with parchment paper. Put the cauliflower florets in the bowl with the batter and toss with a wooden spoon until well coated. Transfer the cauliflower to the baking sheet, place it in the oven, and bake for 20 minutes. Wash the bowl while the cauliflower is baking.
Take the baking sheet out of the oven and pour the cauliflower back into the large bowl. Pour the BBQ sauce over the cauliflower and stir until all the pieces are covered.
Transfer the cauliflower back to the baking sheet, and bake an additional 15 minutes, then flip and bake for another 5-10 minutes, until crispy.
Cool for 5 minutes, then garnish with chopped chives or scallions to serve. Delicious dipped in homemade paleo ranch dressing or cashew ranch dressing!
