Preheat oven to 450 degrees F.
Heat avocado oil on med-high on stove-top, and saute garlic and onion for 3-4 minutes, until soft and translucent.
Remove from heat, and add to blender with 2/3 cup of water. Blend until mostly smooth.
Add flour, tomato paste, paprika, and parsley to blender. Blend until it creates a batter that is thick and smooth.
Transfer into bowl with the cauliflower florets, and mix until cauliflower pieces are completely coated.
Place cauliflower pieces on a baking sheet lined with parchment paper, not touching each other.
Bake for 25 minutes, until the edges brown and crisp. (They will not get completely crispy while in the oven.)
Remove from oven, and let sit for 3-4 minutes to crisp up.
Drizzle with hot sauce and serve immediately.
