Alternative Ingredient Suggestions
If you want to make substitutions based on dietary preferences or ingredient availability, here are a few suggestions:

- Poppy seeds: If you prefer, you can substitute them with sesame seeds, which will still provide a pleasant crunch.

Step-by-Step Instructions
- Preheat your oven to 400°F (200°C).
- Cut the Brussels sprouts, leeks, sweet potatoes, mushrooms, and garlic into bite-sized pieces and place them on a baking sheet.
- Drizzle the olive oil over the vegetables and sprinkle with salt. Toss to coat evenly.
- Roast the vegetables in the preheated oven for 20-25 minutes, or until the sweet potatoes are tender and the vegetables are slightly browned. Halfway through, toss them for even roasting.
- While the vegetables are roasting, cook the pasta according to the package instructions. Drain and let it cool slightly.
- In a small mixing bowl, combine all the dressing ingredients: vegan mayo, olive oil, apple cider vinegar, agave, Dijon mustard, poppy seeds, salt, and onion powder. Whisk together until smooth.
- Once the vegetables are done roasting, allow them to cool for a few minutes before adding them to a large mixing bowl with the pasta.
- Pour the creamy poppy seed dressing over the pasta and roasted vegetables, tossing until everything is evenly coated.
- Serve the pasta salad immediately, or refrigerate it for later. It tastes great both warm and chilled.
