For the roasted butternut squash:
- 2-3 cups butternut squash, diced into ½ inch cubes
- 1 tablespoon olive oil
- ½ teaspoon kosher salt
- ¼ teaspoon freshly ground black pepper
For the salad:
- 2 cups cooked mixed grains, 250g
- 2 cups cooked Puy lentils, 250g
- 2 cups shredded chicken, from about 2 chicken breasts
- 3 cups wild rocket (arugula), 60g
- ¾ cup pomegranate arils
- ¼ cup dried sour (tart) cherries
- ½ cup crumbled feta cheese, 100g
For the harissa dressing:
- 2 tablespoons rose harissa paste
- 1 tablespoons tahini
- 2 tablespoons extra virgin olive oil
- 2 tablespoons water
- ½ lemon, juiced (about 2 tablespoons lemon juice)
- ½ teaspoon maple syrup
- ½ teaspoon kosher salt
How To Make Costco Autumn Grain Salad
- Roast the squash: Preheat the oven to 400°F (200°C). On a parchment-lined baking sheet, toss the butternut squash cubes with olive oil, salt, and pepper. Roast for 30 minutes, flipping halfway through, until tender and golden. Set aside to cool.
- Make the dressing: While the squash roasts, add all the dressing ingredients—rose harissa, tahini, olive oil, water, lemon juice, maple syrup, and salt—to a small bowl. Whisk until smooth and combined.
- Assemble the salad: In a large bowl, combine the cooled butternut squash, cooked mixed grains, lentils, shredded chicken, arugula, pomegranate arils, and dried sour cherries. Pour the harissa dressing over the top and toss well to coat everything.
- Add feta and serve: Gently fold in the crumbled feta cheese, or sprinkle it on top of individual portions when serving.

Recipe Tips
- How to save time on prep? Using pre-cooked grain and lentil pouches is a fantastic shortcut. You can also often find pre-diced butternut squash in the produce section.
- Can I make this vegetarian or vegan? Easily. For a vegetarian version, simply omit the chicken. For a vegan version, omit the chicken and use a vegan feta substitute or skip the cheese altogether.
- How to easily de-seed a pomegranate? Cut the pomegranate in half. Hold one half, cut-side down, over a bowl and firmly whack the back of it with a wooden spoon. The seeds (arils) will fall right out.
- What if I can’t find rose harissa? Regular harissa paste will work fine. Rose harissa is slightly milder and more floral. If using regular harissa, you may want to start with a little less and add more to taste.
What To Serve With Autumn Grain Salad
This is a complete and satisfying meal all on its own. However, it also pairs nicely with:
- A slice of warm, crusty sourdough bread
- A cup of creamy tomato soup
- Warm pita bread
How To Store Autumn Grain Salad
- Refrigerate: Store leftovers in an airtight container in the refrigerator for up to 3 days. If possible, store the arugula separately and add it just before serving to prevent it from wilting.
