Preheat oven to 400 degrees.
Rinse the cauliflower head and pat dry. Remove the outer leaves and stem. Create a flat base but be sure head stays in tact.
In a small bowl, combine Serious Foodie Sri Lanka Coconut Lime Hot Sauce, crushed garlic, lime juice, spice rub, garlic powder, onion powder, salt, pepper, and soy sauce in a bowl.
Place the prepped cauliflower in a bowl (core up) and brush with sauce. Flip over and brush top part with sauce. Carefully plan to dutch oven or baking pan and drizzle any remaining sauce on top. Use a basting brush to fully coat.
Pour vegetable broth into the bottom of the roasting pan.
Cover the bake for 40 minutes or until tender. Increase heat to 425 degrees, remove cover and bake for an additional 5 minutes to brown.
Once done, carefully remove cauliflower from pan. Drizzle with additional Coconut Lime Sauce and top with chopped cilantro and chopped peanuts. Serve warm with lime wedges.
