Steps
1. Preheat the oven to 425°F (220°C).
2. In a mixing bowl, toss the cauliflower florets with olive oil, chili powder, cumin, salt, and pepper until evenly coated.
3. Spread the cauliflower on a baking sheet and roast for 20 minutes, or until golden and tender, flipping halfway through.
4. While the cauliflower is roasting, prepare the avocado-lime crema by blending the avocado, lime juice, and cilantro until smooth. Add water if needed for consistency.
5. Warm the corn tortillas in a skillet over medium heat for about 30 seconds on each side.
6. Assemble the tacos by placing the roasted cauliflower in the tortillas, drizzling with avocado-lime crema, and adding any optional toppings.
7. Serve immediately and enjoy your flavorful tacos!
