Preparation Steps

• Preheat oven to 375°F (190°C). Grease a 9x13 inch baking dish.
• Heat olive oil in a large skillet over medium heat. Add onion and garlic and cook until softened, about 5 minutes.
• Add broccoli, cauliflower, and carrots to the skillet and cook for 5-7 minutes, until slightly tender.
• In a bowl, combine cream of mushroom soup, milk, salt, and pepper. Pour over the vegetables in the skillet and stir to combine.
• Pour the vegetable mixture into the prepared baking dish. Sprinkle with shredded cheddar cheese.
• Bake for 30-35 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
• Let cool for a few minutes before serving.
