Prepare the cilantro lime ranch first, so the flavors have time to blend. Zest the lime, then squeeze the juice from half, and cut the other half into wedges for serving. You’ll need about 1 Tbsp lime juice. Finely chop about 1 Tbsp cilantro and one green onion.
Combine the ingredients for the cilantro lime ranch in a bowl (mayonnaise, greek yogurt, 1 Tbsp lime juice, 1/2 tsp lime zest, garlic powder, onion powder, chopped cilantro, chopped green onion, salt). Refrigerate the cilantro lime ranch until you’re ready to eat.
Next, preheat the oven to 400ºF. Line a baking sheet with parchment paper. Cut the head of cauliflower into florets, then place them in a bowl. In a separate small bowl, combine the ingredients for the taco seasoning (chili powder, smoked paprika, cumin, cayenne, oregano, salt, and some freshly cracked pepper). Drizzle the olive oil over the cauliflower, followed by the taco seasoning, then toss until the cauliflower is evenly coated in oil and spices.
Spread the seasoned cauliflower out over the prepared baking sheet. Roast the cauliflower in the preheated oven for 20-30 minutes, or until it’s brown and crispy on the edges.
Add the undrained can of black beans to a small sauce pot and heat over medium-low, stirring occasionally, until heated through (if making the bowls for meal prep, skip heating the beans).
Add 1 Tbsp cooking oil to a large skillet and heat over medium. Once the oil is hot and shimmering, add the corn. Cook the corn, stirring only occasionally, until it is browned and blistered (about 7-8 minutes). Season with a pinch of salt and pepper.
Slice the grape tomatoes, roughly chop the cilantro, and slice a green onions for garnish.
To build the bowls, divide the roasted cauliflower, beans, corn, and tomatoes between four bowls or containers. Top with a pinch of cilantro, sliced green onion, and a wedge of lime. Drizzle the cilantro lime ranch over top just before eating.
Top with grilled tofu, tempeh, or your fave lentils to give this bowl a protein boostt! Top over rice if you’re looking to add carbs, or on a bed of mixed greens if you’re craving even more veggies!
