Preheat oven to 425 degrees F. Lightly oil a baking sheet or coat with nonstick spray.
Place cauliflower florets in a single layer onto the prepared baking sheet. Add olive oil, garlic, cumin, chili powder and paprika; season with salt and pepper, to taste. Gently toss to combine. Place into oven and bake for 12-14 minutes, or until tender and golden brown.
Stir in tortilla chips in a single layer. Top with black beans and cheese.
Place into oven and bake until heated through and the cheese melts, about 5-6 minutes.
Serve immediately, topped with tomato, guacamole, onion, jalapeno and cilantro.
