1-Preheat your oven: Start by preheating your oven to 420°F and lining a baking sheet with parchment paper for easy cleanup.

2-Chop and season cauliflower: First, chop the cauliflower into florets and toss them with 3 tablespoons of olive oil, taco seasoning to taste, and salt.

3-Roast cauliflower: Spread the mixture evenly on the baking sheet and roast for 25 minutes until it’s golden and crispy.

4-Prepare the sauce: While that’s happening, whisk together the sauce by combining 1/2 cup mayonnaise, 1 tablespoon sour cream, and sriracha to your liking.

5-Assemble nachos for melting cheese: Once the cauliflower is done, gather it in the center of the pan. Add the 15 oz can of drained and rinsed black beans, 1/2 cup shredded cheddar cheese, and 1 sliced jalapeño on top, then pop it back in the oven until the cheese melts.

6-Final toppings and serving: For the final touch, remove it from the oven and top with 1 diced tomato, 1 diced avocado, 1 chopped scallion, 1/4 cup pickled red onions, chopped fresh cilantro, and a drizzle of the prepared sauce.

7-Serve immediately: Serve it right away for the best texture and taste that everyone will enjoy.
