There are so many condiments that you can make at home! If you make your dipping sauce at home, you can control how much sugar and spice it has. One thing I love drizzling on my cauliflower is my homemade teriyaki sauce. It's lower in sugar than the store brand. It's also delicious with ranch, marinara sauce, or pesto.
I also like to dip the cauliflower into my homemade Green goddess dressing. It has the perfect amount of zest!
