There are so many things to do with cauliflower, but this one is special!
Preheat the oven to 400F. Wash and trim the cauliflower, cutting the stem so the cauliflower head sits flat. Place in a pie plate or roasted pan. Brush with olive oil and season with pepper. Roast for 1 1/4 to 1 1/2 hours until softened and browned.
In a small saucepan over medium heat, bring sriracha sauce, honey, vinegar, shallot, garlic, and ginger to a boil. Brush evenly over cauliflower.
Place cherry tomatoes all around the cauliflower. Bake the chile sauce covered cauliflower for 15 minutes more. Garnish with chopped parsley (or cilantro).
