Preheat your oven to 375°F and grease your casserole dish with olive oil.
Steam cauliflower until tender but not mushy. Drain and set aside.
In a skillet, sauté vegan chicken in olive oil until browned and slightly crispy, about 5 minutes.
Toss in coconut bacon and cook 2 more minutes to bring the flavor drama.
In a bowl, whisk almond milk, arrowroot starch, nutritional yeast, garlic powder, onion powder, dill, parsley, salt, and pepper.
Mix everything—cauliflower, vegan chicken, bacon, sauce, and cheese—into a bowl like you’re the CEO of flavor.
Pour into the casserole dish, smooth the top, and sprinkle extra cheese on top (because we’re not savages).
Bake uncovered for 25 minutes until golden and bubbly like it knows it’s hot.
Let cool 5 minutes, garnish with chives, and serve that sass on a plate.
