Preheat your oven to 425°F (220°C).
In a large bowl, combine the cauliflower florets, 2 Tablespoons of olive oil, 1 tablespoon of lemon juice, 1 tablespoon ground turmeric, salt, and pepper. Toss to coat the cauliflower evenly.
Spread the seasoned cauliflower out in a single layer on a baking sheet lined with parchment paper or a silicone baking mat.
Roast in the preheated oven for 25 -35 minutes or until the cauliflower is tender and lightly browned, stirring and flipping once or twice during cooking.
While the cauliflower is roasting, heat 1 tablespoon of olive oil in a large skillet over medium heat.
Add the minced garlic, green beans and corn, to the skillet sauté for a minute.
Season with ground cumin, smoked paprika, salt, and pepper. Continue to sauté the vegetables for 5-7 minutes or until they are tender and slightly caramelized.
Once the cauliflower is done roasting and the corn and green beans are cooked, combine them in a serving dish. Toss everything together gently.Taste and adjust the seasoning if needed. Serve and enjoy!
