Preheat the oven to 425°F (220°C). In a large bowl, whisk together the flour, water, garlic powder, onion powder, smoked paprika, salt, and pepper until smooth and well combined.
Dip each cauliflower floret into the batter, ensuring it’s thoroughly coated. Shake off any excess and arrange the florets on a lined baking sheet.
Bake in the preheated oven for 25-30 minutes, flipping halfway through, until golden brown and crispy.
Once the cauliflower is baked, remove it from the oven, and immediately toss it with the buffalo sauce until evenly coated.
While the cauliflower soaks up the buffalo flavor, warm the tortillas in a dry skillet over medium heat for about 30 seconds on each side or until pliable.
On each tortilla, layer the buffalo cauliflower, a handful of shredded lettuce, a few avocado slices, and some red cabbage.
Drizzle with ranch dressing and sprinkle fresh cilantro on top.
Serve the tacos immediately while warm, and enjoy the spicy twist on a classic taco!
