In a blender, add all adobo sauce ingredients and blend until smooth
In a large pan over medium heat, add olive oil, cauliflower and onions and season with salt and pepper
Cook for 10-12 minutes, stirring often, until cauliflower has browned, is tender and onions are caramelized
Reduce heat to low and stir in adobe sauce and remaining pineapple chunks
Simmer for 8 minutes, letting the sauce reduce, coating the cauliflower, then stir in the cilantro and lime juice
Fill your tortillas with the cauliflower adobo and top with all of your fav taco toppings!
