Rinse the quinoa and combine with 0.5 cup of water in a small saucepan; bring to a boil, then simmer covered for 15 minutes until fluffy.
In a medium bowl, combine the ground turkey, garlic powder, onion powder, sea salt, black pepper, and chopped fresh parsley.
Roll the turkey mixture into 1-inch meatballs, ensuring they are uniform for even cooking.
Heat the olive oil in a large skillet over medium heat and brown the meatballs on all sides until cooked through.
Add the diced red bell pepper to the skillet during the last 4 minutes of cooking, sautéing until tender-crisp.
Toss in the baby spinach and cook just until wilted, then remove from heat.
Assemble the bowl by layering the quinoa, meatballs, and vegetables, finishing with a bright squeeze of lemon juice.
