Ingredient Notes & Substitutions

The full list of ingredients to make Costco quinoa salad is above. Below are notes about some of the ingredients along with ideas for substitutes.

Quinoa – comes in a variety of colors, all are similar in taste, but some may take a little bit longer to cook. You can use any color of quinoa in this salad.

The Costco recipe is made with white quinoa, but I like to add a little more color and use red quinoa in my homemade version.

Kale – is a sturdy green that holds up well in this salad. It can be replaced with chopped spinach if you don’t care for kale or if kale isn’t available.

Cucumber – any type of fresh cucumber that you have on hand will work in this recipe. English cucumber is my preference; it has a sweeter flavor and smaller seeds.

Substitute the cucumber with small zucchini.

Lentils – small lentils such as red lentils or French lentils work the best in this recipe. They are similar in size to rice and quinoa.

Rice – I use long grain brown rice which isn’t as starchy and sticky like short grain rice is, but you can use any type of cooked rice that you like.

Substitute rice with a cup of quinoa.

Vinegar – apple cider vinegar adds a bit of a fruity flavor to the dressing, and it can be replaced with red wine vinegar, white wine vinegar, and even balsamic vinegar.

White vinegar is not recommended in this recipe, its flavor is too strong and sharp.

Maple Syrup – adds just the right amount of sweetness to this delicious salad. Honey is a good substitute for maple syrup in this salad.

Extra Virgin Olive Oil – Extra virgin is lighter in flavor and perfect for making salads. It can be substituted with avocado oil or regular olive oil.

How to make Costco quinoa salad ahead of time

This delicious salad is so easy to make ahead of time! Cook the quinoa, rice and lentils up to two days ahead and store them separately in the refrigerator.

Chop up the vegetables, and store the chopped veggies separately in the refrigerator for two to three days.

When it’s time to serve the salad, combine all of the salad ingredients in a large serving bowl. In a smaller bowl whisk the dressing ingredients together and stir in the dressing and herbs.


This healthy salad is so versatile! You can follow the recipe instructions or get creative and try making this great salad in different ways! Here are some suggestions.

  • Change the fresh vegetables – use any combination of cooked chopped mushrooms, steamed chopped broccoli, carrots or chopped asparagus.
  • Greek quinoa salad – Toss in 1/4 to a half cup of kalamata olives and 1/4 cup of feta cheese.
  • Spicy Quinoa Salad – add 1/2 to a teaspoon of red pepper flakes to the salad.

Serving suggestions

Serve this zesty quinoa salad as a main dish or a side dish. It tastes great topped with a dash of lemon zest alongside grilled pork chops, burgers or chicken. It’s also perfect to bring to your next potluck!

Recipe tips and questions


  • This easy quinoa salad recipe is a great way to use up leftover rice or quinoa.
  • Play around with the ratio of rice, quinoa, and lentils to your preference. There should be about 2 1/2 cups of whole grains and lentils. I like an equal amount of rice and quinoa and fewer lentils. If you love lentils, add more of them! This salad is that versatile!


Can you freeze quinoa salad?

Freezing Costco quinoa salad is not recommended, the vegetables and dressing add a considerable amount of moisture to this salad and will be soggy once it has thawed out. You can, however, freeze plain-cooked quinoa and rice. Place cooked room temperature quinoa and rice into an airtight bag, for up to three months. Thaw it out in the refrigerator overnight and use it to make the salad.

Is Costco quinoa salad vegan?

Yes, this salad is vegan. It’s a good source of protein and fresh veggies!
