Meanwhile in a sauce pan over, medium heat, cook onions and garlic in butter until caramelized, 5-7 minutes. Toss kale with onion, garlic, and butter from pan. Season with salt, pepper and red pepper flakes.
Remove your CAULIPOWER pizza crust from the box and the plastic wrapping, and place on a clean surface.
Top with the kale mix, add sun-dried tomatoes, top with mozzarella and bake for 13-15 minutes.
While pizza is cooking, add balsamic and coconut sugar to a small sauce pan over low flame and simmer until a glaze forms, about 10 minutes.
When pizza is done, drizzle with balsamic glaze and serve.
