Ingredients
Instructions
- Preheat oven to 400°F. Halve the squashes lengthwise, then scoop out the seedy area with a spoon. Place on a lightly oiled baking sheet and toss with 1 tablespoon olive oil, salt and pepper. Roast cut side down for 20-25 minutes until soft and golden.
- While squash roasts, bring 1 cup water and the stock concentrate to a boil in a small pot. Add quinoa, cover and simmer for 15 minutes.
- Finely chop mushroom caps and stems. Mince shallot and garlic. Halve, seed and finely dice tomatoes. Strip thyme leaves and chop.
- Heat 1 tablespoon butter in a large pan over medium heat. Add shallot and cook 2-3 minutes until soft. Add 1 tablespoon olive oil, mushrooms, tomato and thyme. Cook 5-6 minutes until very soft. Add garlic and cook 30 seconds. Season with salt and pepper.
- Add cooked quinoa to the pan and toss to combine. Season with salt and pepper.
- Remove squash from oven. Stuff with quinoa mixture. Heat broiler to high. Sprinkle squash with Parmesan cheese and broil until cheese is melted and golden.

Recipe Tips
For a vegan version, substitute the butter with additional olive oil and omit the Parmesan or use a vegan alternative.
Make sure to scoop out the squash seeds thoroughly to create enough room for the filling.
If you don’t have veggie stock concentrate, you can use 1 cup of vegetable broth instead of water and skip the concentrate.
