Instructions

1. Preheat the oven to 425° F.
2. Cut cauliflower into small florets
3. Heat the olive oil in a large skillet over high heat. When the oil shimmers, add the cauliflower and onion. Cook, stirring occasionally, until the cauliflower is charring, about 5 minutes. Add the salsa. Reduce the heat to medium and simmer until the sauce has thickened slightly, about 10 minutes. Remove from the heat.
4. Warm the tortillas for 30 seconds to 1 minute in the microwave, until pliable. On a baking sheet, rub the tortillas with olive oil. Lay each flat and then layer evenly with cheese and cauliflower. Fold the other half of the tortilla over the filling, gently pushing to adhere. Transfer to the oven and bake for 5-8 minutes, then flip and cook another 5 minutes more, or until the cheese has melted and the tortillas are crisp.
5. Serve the tacos topped with avocado, lettuce, limes, and any other desired toppings.
