Roast the cauliflower: Preheat the oven to 425°F (220°C).On a large sheet pan, toss 1 medium cauliflower head cut into florets, 1 can black beans (rinsed), and 1 red onion with 1 to 2 tablespoons extra virgin olive oil, 2 teaspoons chili powder, 2 teaspoons ground cumin, 1 teaspoon smoked paprika, 1 teaspoon dried oregano, 1 teaspoon salt, and pepper. Spread into an even layer.Roast for 25 to 30 minutes until the cauliflower is tender and browned.
Make the dressing: While the vegetables roast, cook the rice according to the package directions, unless you're using leftover rice.In a small bowl, whisk together 3 tablespoons extra virgin olive oil, 3 tablespoons lime juice, lime zest if using, ½ cup fresh herbs (chopped), 1 small clove garlic (grated), ½ teaspoon salt, and some black pepper.
Toss everything together: Add 3 cups cooked rice, ¾ cup shredded cheese, and the lime dressing directly to the hot sheet pan.Toss well until the rice is evenly coated, the cheese starts to melt, and the rice picks up the flavorful browned bits from the pan.Tip If the mixture seems dry, squeeze in extra lime juice or olive oil.
Serve: Divide the cauliflower burrito bowl among serving bowls. Enjoy as is or top with diced tomatoes or pico de gallo, Greek yogurt or sour cream, hot sauce, and a squeeze of fresh lime, if you like. Enjoy warm.
