# Steps:
01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, combine bell pepper, zucchini, red onion, cherry tomatoes, and broccoli florets. Drizzle with olive oil and season with salt and black pepper. Toss until evenly coated. Spread vegetables in a single layer on the prepared baking sheet.
03 - Place baking sheet in preheated oven and roast for 20 to 25 minutes, stirring once halfway through cooking, until vegetables are tender and lightly caramelized.
04 - While vegetables roast, bring a large pot of salted water to boil. Add elbow macaroni and cook according to package directions until al dente. Drain in a colander and set aside.
05 - Melt unsalted butter in a large saucepan over medium heat. Whisk in all-purpose flour and cook for 1 minute, stirring constantly to create a smooth paste.
06 - Gradually pour in whole milk while whisking continuously. Maintain medium heat and stir constantly until the mixture thickens, approximately 3 to 5 minutes.
07 - Reduce heat to low. Add shredded cheddar cheese, mozzarella cheese, and grated Parmesan cheese. Stir continuously until completely melted and smooth. Season with mustard powder, garlic powder, salt, and pepper to taste.
08 - Add cooked macaroni and roasted vegetables to the cheese sauce. Fold ingredients together gently until evenly coated and heated through.
09 - Transfer to serving dishes immediately. Garnish with additional grated Parmesan cheese if desired.
