- 1 ½ teaspoon chili powder
- ½ teaspoon cumin
- ½ teaspoon smoked paprika
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 (15 oz) can black beans, drained and rinsed
- 8 corn tostada shells
- 1 cup queso fresco, crumbled

For Quick Pickled Red Onion:
- 1 small red onion, thinly sliced
- ½ cup apple cider vinegar
- ½ cup water
- 1 tablespoon sugar
- 1 teaspoon salt
Directions
Step 1: Prep and Roast the Cauliflower
- Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
- Toss cauliflower florets with olive oil, chili powder, cumin, smoked paprika, salt, and black pepper until evenly coated.
- Spread cauliflower in a single layer. Roast for 25-30 minutes, flipping halfway through, until golden and tender with crispy edges.
Step 2: Make Quick Pickled Onion
- In a jar or bowl, whisk together apple cider vinegar, water, sugar, and salt.
- Add sliced red onion. Let sit at room temperature for at least 20 minutes, stirring occasionally.
Step 3: Warm the Black Beans
- While the cauliflower roasts, heat the black beans in a small saucepan over medium heat for 3-5 minutes until hot. Season to taste with salt and pepper.
Step 4: Assemble the Tostadas
- Arrange tostada shells on plates.
- Spread a layer of black beans on each shell. Top with roasted cauliflower.
- Sprinkle generously with queso fresco, then add pickled onions, cilantro, and avocado slices, if using.
- Serve with lime wedges for squeezing.
Notes
- You can make the pickled onions up to a week in advance; store in the fridge.
- For ultra-crispy tostadas, bake them in a 350°F (175°C) oven for 5 minutes.
- Swap queso fresco with another mellow cheese like feta for a zippy twist.
Variations
- Spicy Tostadas: Add diced jalapeños or a sprinkle of red chili flakes to the cauliflower before roasting.
- Vegan Version: Use vegan cheese or cashew queso in place of queso fresco.
- Southwest Crunch: Top with shredded lettuce and a drizzle of hot sauce or salsa for extra flavor and crunch.
