Preparing Costco Copycat Quinoa Salad
Ingredients You’ll Need
For the Salad
- 1 cup quinoa
- 1 Roma tomato
- 1 mini cucumber
- ½ red bell pepper
- ½ green bell pepper
- ¼ cup fresh cilantro
For the Dressing
- Juice of 1 lime (25–30 ml)
- 2 tablespoons avocado oil (or extra virgin olive oil)
- ½ teaspoon ground cumin
- ½ teaspoon salt
- ⅛ teaspoon ground black pepper
- ¼ teaspoon sugar

Is Quinoa High in Protein?
One of the reasons I love cooking with quinoa is that it’s naturally higher in protein than many other grains. It’s also a complete protein, meaning it contains all nine essential amino acids, making it an excellent choice for vegetarian meals.
Combined with fresh vegetables and healthy fats from avocado oil, this salad is both nourishing and satisfying. If you’d like to make it even higher in protein, try serving it with grilled chicken, shrimp, salmon, or chickpeas.
How to Make Copycat Costco Quinoa Salad
Step 1: Cook the quinoa
Add the quinoa and two cups of water to a saucepan. Cook over medium-low heat until approximately half of the water has been absorbed, stirring occasionally, about 10 minutes.

Cover with a lid, remove from the heat, and let it sit for 5–8 minutes.

Fluff with a fork and allow it to cool completely.

Step 2: Prepare the vegetables
While the quinoa cools, wash and finely chop the tomato, cucumber, bell peppers, and cilantro. I like cutting everything into small, even pieces so you get a little bit of everything in every bite.
Step 3: Make the dressing
Juice the lime into a small bowl. Add the avocado oil, cumin, salt
, pepper, and sugar. Whisk until well combined.
Tips for the Best Quinoa Salad
- Let the quinoa cool completely before mixing to keep the vegetables crisp.
- Rinse the quinoa before cooking to remove any bitterness.
- Finely dice the vegetables for the best texture.
- Taste before serving and add an extra squeeze of lime if you’d like a brighter flavour.
- This salad tastes even better after a few hours in the refrigerator as the flavours meld together.
Step 4: Assemble the salad
Once the quinoa has cooled, combine it with the chopped vegetables. Pour the dressing over top and toss until everything is evenly coated.
Serve immediately or refrigerate until ready to enjoy.
Variations
This salad is easy to customize depending on what you have available.
Try adding:
- Chickpeas for extra plant-based protein.
- Grilled chicken for a heartier meal.
- Crumbled feta cheese for a creamy, salty finish.

- Green onions for additional freshness.
- Jalapeño for a little heat.
