To prepare the tacos de jamaica vegan hibiscus, you'll need: 1 pound sourdough tortillas 2 tablespoons olive oil 1 teaspoon kosher salt 1/2 teaspoon cayenne pepper 1 tablespoon chile flakes Instructions Preheat the oven to 375 degrees F. Line a baking sheet with foil and set aside. Heat the oil over medium-high heat until shimmering. Add the onion and cook until softened, about 5 minutes. Stir in the garlic, cumin, and paprika. Cook, stirring, until the onions and garlic are lightly browned, 2 to 3 minutes more. Remove the pan from the heat and add the tomatoes. Toss to coat. Transfer the mixture to the baking dish. Bake for 20 minutes or until heated through. Serve warm with guacamole.
