In a medium saucepan, combine rinsed quinoa and vegetable broth. Bring to a boil over high heat.
Reduce heat to low, cover, and simmer for 15 minutes until liquid is fully absorbed. Remove from heat and let stand covered for 5 minutes.
While quinoa cooks, pat shrimp dry with paper towels. In a bowl, toss shrimp with smoked paprika, garlic powder, salt, and black pepper.
Heat olive oil in a large skillet over medium-high heat. Add shrimp and sauté for 2 to 3 minutes per side until they turn pink and opaque.
Fluff the quinoa with a fork and divide equally among four bowls or meal-prep containers.
Layer each bowl with equal portions of baby spinach, cherry tomatoes, and diced cucumber.
Place the sautéed shrimp on top of the vegetables. Finish each bowl with avocado slices, a drizzle of lemon juice, and chopped parsley.
