About the Ingredients

2 cups (200g) quinoa, rinsed

Use white or tri-color quinoa. Substitute with couscous or farro for a different texture.

4 cups (960ml) vegetable broth

Low-sodium broth keeps the dish lighter. You can use water with a pinch of salt if needed.

1 large (200g) cucumber, diced

English cucumber has fewer seeds. Regular cucumber works too; just scoop out the seeds.

1 cup (150g) cherry tomatoes, halved

Grape tomatoes are a sweeter alternative. Use any ripe, colorful variety.

1/2 cup (75g) red onion, finely chopped

Soak in cold water for 10 minutes to mellow the bite. Shallots work as a substitute.

1/2 cup (20g) fresh parsley, chopped

Flat-leaf parsley has more flavor. Curly parsley is fine; or use fresh mint for a twist.

1/4 cup (60ml) extra-virgin olive oil

Good quality olive oil makes a difference. Use avocado oil for a neutral taste.

3 tbsp (45ml) fresh lemon juice

About 1 large lemon. Bottled lemon juice works in a pinch but fresh is better.

1 tsp (5g) Dijon mustard

Adds tang and helps emulsify the dressing. Yellow mustard is a fine substitute.

1/2 tsp (2g) ground cumin

Toasted cumin seeds ground fresh are more aromatic. Skip if you don't have it.

1/2 tsp (2g) salt, plus more to taste

Use kosher salt for even seasoning. Sea salt works too.

1/4 tsp (1g) black pepper

Freshly ground is best. Pre-ground works in a pinch.

Tips & Tricks

• Rinse quinoa thoroughly to remove its bitter coating (saponin).
• Chop vegetables uniformly for even texture and better presentation.
• Let the quinoa cool completely before mixing to prevent wilting the herbs.
• Make the dressing ahead; shake well before using.

Step-by-Step Instructions

1. Cook the Quinoa

In a medium saucepan, combine quinoa and broth. Bring to a boil over high heat, then reduce to low, cover, and simmer for 15 minutes until liquid is absorbed. Remove from heat and let stand covered for 5 minutes. Fluff with a fork and spread on a baking sheet to cool completely.

2. Make the Dressing

In a small bowl, whisk together olive oil, lemon juice, Dijon mustard, cumin, salt, and pepper. Set aside.

3. Combine Vegetables

In a large bowl, add cooled quinoa, cucumber, cherry tomatoes, red onion, and parsley. Toss gently to distribute.

4. Add Dressing

Pour the dressing over the salad and mix well. Taste and adjust seasoning with additional salt and lemon if needed.

5. Chill and Serve

Cover and refrigerate for at least 30 minutes to let flavors develop. Serve chilled or at room temperature, garnished with extra herbs if desired.

Delicious Variations

• Add 1 cup (150g) chickpeas for extra protein and fiber.
• Swap parsley for fresh mint and add 1/2 cup (75g) crumbled feta cheese.
• Stir in 1/2 cup (75g) dried cranberries and 1/4 cup (40g) toasted pecans for a sweet crunch.
