How to make Southwest Veggie and Rice Casserole
Back to contentsPreheat the oven to 191°C. Coat an 8-by-8-inch casserole dish with nonstick cooking spray.
In a large skillet, heat the vegetable oil over medium-low heat. Add the onion and garlic and cook for about 5 minutes, or until the onions have softened. Add the jalapeño and peppers, courgette, chilli powder, and salt to the skillet and stir to combine. Raise the heat to medium and continue to sauté until the vegetables are soft and no liquid remains on the bottom of the skillet, about 10 minutes.
In a large bowl, combine the corn kernels, diced tomatoes and chillies, and black beans. Add the sautéed vegetables, Taco Rice, and shredded cheddar cheese to the bowl and stir until evenly mixed.
Pour the rice and vegetable mixture into the prepared casserole dish and bake for 20 minutes.
Sprinkle the spring onions over the casserole and serve.
