Heat oil in a large non stick skillet over medium heat. Add onion and garlic and cook until soft, about 3 minutes.
Add paprika, cauliflower, salt and oregano. Put a lid on the skillet and cook for 5 minutes, occasionally stirring.
After 5 minutes have elapsed, add the adobo sauce and agave into the skillet. Cook without the lid for 8- 10 minutes longer, or until there is no liquid in the bottom of the pan and the cauliflower is tender.
Put the filling into tortillas, add desired toppings and serve!
