Servings6 medium bowls


  • 1 cup white quinoa (uncooked)
  • 12 oz. asparagus
  • 2 bell peppers (I use 1 orange + 1 yellow)
  • 1 small red onion
  • 12 oz. cherry tomatoes (or grape tomatoes)
  • 1-2 cups fresh baby spinach
  • Salt to taste

For the garlic-balsamic dressing:

  • 1 1/2 Tbsp. balsamic vinegar
  • 2 cloves garlic, minced
  • 1/2 tsp. dried basil


  • Preheat oven to 425°F (218°C). Line a baking sheet with parchment paper*.
  • Cut asparagus into about 1 1/2-inch pieces, woody ends removed. Cut bell peppers and onion into 3/4 to 1 inch squares. Place on baking sheet. Add cherry tomatoes. Salt if desired.
  • Place in oven and roast for 25 minutes, or desired tenderness.
  • Meanwhile, cook the quinoa: Place 1 cup quinoa (rinsed and drained) in a small saucepan with 1 1/2 cups water or vegetable broth. Bring to a light boil over medium-high heat. Then reduce heat to medium-low, cover, and simmer for 20 minutes.
  • In a small bowl, combine dressing ingredients and set aside.
  • When quinoa is done cooking, immediately place in a large bowl and toss with spinach. (The heat from the quinoa will lightly wilt the spinach.)
  • Pour dressing over quinoa and mix well to combine. Add roasted vegetables and stir.
  • Salt to taste (or add fresh basil, or a splash more balsamic if desired). Great served warm or chilled.


*For oil-free roasting: Place a sheet of parchment paper (or Silpat) on the baking pan. Feel free to roast with a drizzle of oil if you prefer, however.
Onions: If you're not a fan of onions, you can omit or replace with another vegetable. (They're fairly strong in this recipe.)
Herbs: Fresh basil or parsley is a flavorful addition as well.
