Instructions:

1. Preheat Oven and Prepare Squash:
- Preheat your oven to 400°F (200°C).
- Place the cubed butternut squash in a large bowl. Drizzle with 2 tsp of olive oil and sprinkle with paprika, 1 tsp of salt, and ground nutmeg. Toss to ensure the squash is evenly coated.

2. Roast Butternut Squash:

4. Prepare Pistachio Pesto:
- In a food processor, combine the garlic, lime juice, pistachio nuts, jalapeno pepper, coriander leaves, 1/4 tbsp olive oil, a dash of salt, and a dash of black pepper. Blend until smooth.

5. Combine Ingredients:

What type of pasta works best for this recipe?

Whole-wheat pasta is used in this recipe, but other types such as penne, fusilli, or spaghetti can work as alternatives. Just ensure to cook according to the package instructions.

Can I make the pesto ahead of time?

Yes, you can prepare the pistachio pesto in advance. Store it in the refrigerator in an airtight container for up to 3 days. You may need to stir or blend it again before using, as it may thicken.

- For a smoother pesto, you can blend the pistachios, garlic, lime juice, coriander leaves, olive oil, dash of salt and pepper in a food processor until the desired consistency is reached.

- Consider using fresh Parmesan cheese for grating to enhance the overall flavor and texture of the dish.

- If you find the pesto to be too thick, you can thin it out with a bit of the pasta cooking water.

- Always taste and adjust the seasoning before serving to achieve the perfect balance.
