Spread chopped veggies on a baking sheet. Using a microplane, grate garlic on top of veggies. Reserve 1 tbsp of avocado oil and drizzle remaining oil on top of veggies. Bake at 475º until the vegetables start to get tender. Stir a couple of times throughout cooking to coat all the veggies with butter and so they cook evenly. When veggies are almost tender, massage reserved oil lightly into kale. Stir kale into veggies and season with salt and pepper. Return to oven and stir every 5-10 minutes until veggies are completely tender. Garnish with cheese of choice.
