This salad is pretty and tasty.  It is also a good protein source along with many other nutrients and fits into a vegan diet as well.

Ingredients (for two servings)

1/3 cup quinoa
1/4 cup diced onion
1 1/2 Tbsp lime juice
1/2 tsp cumin seeds
2 cups spinach

1/2 cup cucumber, diced
1 cup tomato, diced
salt and pepper to taste
1 avocado, sliced
​Garnish with nuts - optional

Directions:

Bring the quinoa and 2/3 cup of water to boil in a small saucepan.  Reduce the heat to medium-low, cover, and simmer until quinoa is tender and water absorbed, about 15-20 minutes.   Add the diced onion and put in a medium bowl and refrigerate until chilled at least 30 minutes.
Stir tomatoes and cucumber into the cooled quinoa.  Season with lime juice, cumin, stir and then add salt and pepper to taste.  Divide the spinach among two plates (you may wilt the spinach for a few minutes in fry pan if desired).  Garnish with sliced avocado and sprinkle with nuts
