Preheat the oven to 425 degrees.
Cut off the cauliflower stems and slice the cauliflower into ½ inch steaks.
Lightly drizzle coconut oil the cauliflower and top with freshly ground black pepper.
Transfer cauliflower steaks onto a nonstick pan and roast in the oven for 10 minutes on each side, until golden.
While it is roasting, pull out a food processor and prepare your pesto.
Add the kale, basil and lemon juice, and process until greens are broken down a bit. Add avocado and salt, and process until smooth. Taste the pesto, and adjust seasonings.
Take the cauliflower out of your oven and transfer it to your favorite plate. Garnish with a serving of your Avocado Kale Vegan Pesto and enjoy it!
