Prep the cauliflower, green onion, and thyme by cutting the cauliflower into florets, slicing the green onion finely, and removing the thyme leaves from the stems before chopping.
In a food processor, rice the cauliflower by pulsing it to form a crumbly texture that resembles rice.
Add the green onion, thyme, and collard greens to the mixture and continue pulsing until well combined.
Scoop the mixture out into a large mixing bowl.
Add the mozzarella, parmesan, eggs, sesame seeds, olive oil, garlic powder, salt, and pepper.
Mix everything well to form a loose batter.
Heat up your waffle iron and spoon the mixture in evenly.
Follow the manufacturer's instructions for cooking.
Remove and serve hot!
