Ingredients

For the Quinoa Base

1 cup dry quinoa
1 .5 cups water
Salt and pepper to taste

For the Rainbow Vegetables

2 Roma tomatoes
2 carrots (or 1/2-3/4 cup shredded carrots)
1 red bell pepper
1 stalk green onion
1 /2 English (hothouse) cucumber
1 /4-1/3 cup finely chopped red onion
1 cup corn (steamed from frozen)
1 can chickpeas (14.5 oz), drained and rinsed

For the Lemon Vinaigrette Dressing

1 .5 lemons, freshly juiced
1 /4 cup avocado oil (or light olive oil)
2 tsp apple cider vinegar (or red wine vinegar)
1 tsp fresh minced garlic from approximately 2 cloves
1 /2 tsp dried oregano leaves
1 /2 tsp salt
1 /2 tsp pepper
1 /4 cup fresh chopped parsley (optional but tasty!)

Instructions

Prepare the Quinoa

1 Rinse and drain your 1 cup quinoa using a fine-mesh strainer or sieve until the water runs clear. This removes the natural coating called saponin that can make quinoa taste bitter.
2 Bring a small pot to medium heat and lightly toast the rinsed quinoa for 2-3 minutes, stirring often to remove any excess water. This optional step really adds to the nuttiness and fluff factor of the quinoa by developing deeper flavors through the toasting process.
3 Add your 1.5 cups water, set burner to high, and bring to a boil. Once boiling, reduce heat to low and simmer, covered with the lid slightly ajar, for 12-13 minutes or until quinoa is fluffy and the liquid has been completely absorbed.
4 Once your quinoa is ready, fluff with a fork and season with salt and pepper to taste. Transfer to a medium bowl to cool completely – this prevents the vegetables from wilting when mixed.

Make the Dressing

5 While the quinoa cooks, whisk together all the dressing ingredients in a small bowl, or add to a mason jar with a tight-fitting lid and shake vigorously for 30 seconds. The emulsification creates a creamy, well-blended dressing that coats every ingredient perfectly.
6 Taste and adjust ingredients as needed – some lemons are more tart than others, so you might want to add a pinch more salt or a drizzle more oil to balance the flavors.

Prep the Rainbow Vegetables

7 Peel carrots and shred using a julienne peeler, box grater, or use pre-shredded carrots for convenience. Chop the shredded carrots into smaller, bite-sized pieces for easier eating.
8 Peel the cucumber and dice into 1/2-inch cubes. English cucumbers have fewer seeds and thinner skins, making them perfect for salads without the watery texture of regular cucumbers.
9 Chop the red bell pepper, green onion, red onion, and Roma tomatoes into uniform 1/2-inch pieces. Consistent sizing ensures every bite has the perfect balance of flavors and textures.
10 Drain and rinse the canned chickpeas thoroughly under cold water, and steam the frozen corn according to package directions, then let cool completely.

Assemble the Salad

11 Combine the cooled quinoa with all prepared vegetables, chickpeas, and corn in a large mixing bowl. The quinoa should be completely cool to prevent wilting the fresh vegetables.
12 Pour the lemon vinaigrette over the salad mixture and toss gently but thoroughly until every ingredient is well-coated with dressing. Use a large spoon or salad tongs to ensure even distribution.
13 You can enjoy this salad immediately for a fresh, crisp texture, or chill in the refrigerator for at least 30 minutes before serving. The chilled version allows the dressing to soak into the salad and amplify the flavors even more.

Pro Tips and Troubleshooting

Professional Techniques:
Always toast the quinoa before adding liquid – this extra step develops deeper, nuttier flavors and prevents mushy texture. Salt the cooking water for quinoa just like pasta water; it seasons the grain from the inside out. Cool ingredients completely before mixing to prevent wilting and maintain optimal textures. Dress the salad in stages – toss with half the dressing, let it sit 10 minutes, then add remaining dressing for better flavor penetration.

Common Mistake Prevention:
Over-mixing can break down delicate vegetables and make the salad mushy – fold ingredients gently with a large spoon rather than stirring vigorously. Under-seasoning is common with grain salads; taste and adjust salt levels after the salad has rested, as flavors meld and may need rebalancing. Watery vegetables like tomatoes and cucumbers should be salted lightly and drained for 10 minutes before adding to prevent diluting the dressing.

Storage and Make-Ahead Strategies:
This salad actually improves overnight as flavors meld, making it perfect for meal prep. Store in airtight glass containers for up to 5 days in the refrigerator. Add delicate ingredients like avocado or fresh herbs just before serving to maintain optimal texture and color. Freeze individual portions without dressing for up to 3 months – thaw overnight and dress fresh for quick meals.

Scaling and Presentation:
Double or triple the recipe easily for large gatherings – just ensure you have adequate mixing bowl space. Serve in a clear glass bowl to showcase the beautiful rainbow colors. Garnish with fresh herb sprigs and lemon wedges for restaurant-quality presentation that makes this simple salad look gourmet.

This rainbow quinoa salad proves that healthy eating doesn’t have to be boring or complicated – sometimes the most satisfying meals are the ones that let fresh, quality ingredients shine in their natural glory.
