Boil 2 cups of water or vegetable broth in a medium saucepan.

Add 1 cup of rinsed quinoa to the boiling water, reduce heat to low, cover, and simmer for 15 minutes.

Remove from heat and let sit covered for 5 minutes, then fluff with a fork.

While quinoa cooks, wash and chop the vegetables: halve cherry tomatoes, dice cucumber and bell pepper, slice avocado, and thinly slice red onion.

In a large bowl, combine spinach or mixed greens with chopped parsley.

Assemble the bowl by starting with a base of quinoa, then layer with spinach mixture, cherry tomatoes, cucumber, bell pepper, avocado, and red onion.

Drizzle with olive oil and lemon juice, then season with salt and pepper to taste.

Toss the ingredients together and serve immediately.
