Preheat the oven to 450F convection or 475F. Line a baking sheet with parchment paper.
To a high-speed blender, add 1 cup pineapple, tomato, oil, soy sauce, spices, 1 teaspoon salt, and garlic. Blend on high until smooth. Transfer about ½ cup to a medium bowl and set aside.
To the baking sheet, add the chicken, cauliflower, and the rest of that sauce/marinade (scrape out every last bit). Toss to coat well, then spread into an even layer. Sprinkle the remaining ½ teaspoon salt evenly over along with some black pepper. Bake for 20-25 minutes or until the cauli and/or chicken are beginning to char/brown.
Scatter the remaining ½ cup pineapple all over, then turn the oven to broil on high. Place the baking sheet on the top rack and broil for 2-4 minutes or until everything is a little charred (keep an eye on it).
To the reserved sauce, stir in the yogurt and lime until combined.
For tacos: serve the chicken/cauli a warm tortilla with avocado slices, topped with the sauce, onion and/or radish, cilantro, and a squeeze of lime.
For bowls: to bulk up your bowl, start with a base of cooked rice or quinoa. Add the chicken/cauli to your bowl. Top with sauce and all the toppings along with some feta cheese and a side of tortilla chips.
For quesadillas: mix the chicken/cauli with shredded cheese (you can also mix in some cilantro and pickled onion or radish), then scoop it into a tortilla and either pan-fry or bake in the oven until crisp and melted.
