Preheat oven to 375°F and lightly grease or spray a 9x13 baking dish.
Make the pineapple salsa in a large bowl and refrigerate until ready to serve.
Season:
In a large bowl, combine the olive oil and curry powder. Add the cauliflower florets and toss to combine. Transfer the cauliflower to a 9 x 13-inch baking dish.
Roast:
Roast cauliflower for about 30 minutes, until the tops begin to turn golden brown, tossing after about 20 minutes.
Serve:
Prior to serving, warm the tortillas.
Fill the tortillas with the roasted cauliflower and pineapple salsa. Top with sour cream, if using.
