Roasting the vegetables in this pasta primavera recipe adds a depth of flavor that is simply irresistible. Toss a mixture of bell peppers, broccoli, and carrots with olive oil, salt, and pepper, and roast them in the oven until they are caramelized and tender. Meanwhile, cook your favorite pasta until al dente. In a separate pan, sauté garlic and onions until fragrant, then add in the roasted vegetables and cooked pasta. Toss everything together with a splash of lemon juice and a sprinkle of Parmesan cheese for a delicious and satisfying meal.
