Roast the Cauliflower Preheat the oven to 425°F. In a large bowl, coat the cauliflower with 2 tablespoons of the oil and the taco seasoning. (If your taco seasoning isn’t salted, mix in 1/2 tsp kosher salt.) Spread the florets out on a rimmed baking sheet without crowding them. Roast 30–35 minutes, tossing once halfway through, until browned and tender.
Prepare the Bean Mixture Warm the remaining tablespoon of oil in a large skillet over medium heat. Add the red onion and cook until softened, about 3–5 minutes. Stir in the adobo sauce, granulated garlic, and cumin; cook for 1 minute. Add the black beans, tomatoes, corn, and 1/2 teaspoon kosher salt. Let everything simmer gently for 5–7 minutes, or until slightly thickened. Finish with the cilantro and lime juice.
Blend the Jalapeño Ranch Place all dressing ingredients into a food processor and blend until completely smooth.
Assemble the Bowls Spoon the warm bean mixture into four bowls. Add generous portions of the roasted cauliflower, any optional toppings you like, and a drizzle of the Jalapeño Ranch.
Tip:
Every component also works beautifully inside a toasted tortilla if you’d rather transform this into tacos.
