# How-To Steps:
01 - Preheat oven to 425°F. Line a baking sheet with parchment paper. In a large bowl, combine diced bell pepper, zucchini, red onion, halved cherry tomatoes, and broccoli florets. Drizzle with 2 tablespoons olive oil and season with 1/2 teaspoon salt and 1/4 teaspoon black pepper. Toss until evenly coated.
02 - Spread vegetables evenly on the prepared baking sheet. Roast for 20 to 25 minutes, stirring once halfway through cooking, until vegetables are tender and slightly caramelized.
03 - While vegetables roast, bring a large pot of salted water to a boil. Add 10 ounces elbow macaroni and cook according to package instructions until al dente. Drain in a colander and set aside.
04 - In a large saucepan, melt 2 tablespoons unsalted butter over medium heat. Whisk in 2 tablespoons all-purpose flour and cook for 1 minute, stirring constantly to create a roux.
05 - Gradually whisk in 2 cups whole milk while stirring constantly to prevent lumps. Continue cooking and stirring for 3 to 5 minutes until the mixture slightly thickens.
06 - Reduce heat to low. Add 1 1/2 cups shredded cheddar cheese, 1/2 cup shredded mozzarella cheese, and 1/4 cup grated Parmesan cheese. Stir continuously until all cheese is melted and the sauce is smooth.
07 - Stir in 1/2 teaspoon mustard powder and 1/4 teaspoon garlic powder. Season with salt and pepper to taste.
08 - Add the cooked macaroni and roasted vegetables to the cheese sauce. Stir gently until all pasta and vegetables are well coated and heated through.
09 - Transfer to serving dishes immediately while hot. Garnish with additional grated Parmesan cheese if desired.
