01 - Combine rinsed quinoa, water, and salt in a medium saucepan. Bring to a rolling boil over medium-high heat. Reduce heat to low, cover tightly, and simmer for 15 minutes until the liquid is fully absorbed. Remove from heat and let stand, covered, for 5 minutes. Fluff gently with a fork.
02 - While the quinoa cooks, warm olive oil in a large skillet over medium heat. Add the diced bell pepper and sauté for 2 to 3 minutes until slightly softened. Add the cherry tomatoes and cook for an additional 2 minutes. Fold in the baby spinach and stir until just wilted, about 1 minute. Remove from heat.
03 - Heat a small nonstick frying pan over medium-low heat. Cook the eggs to your preference — fried or poached work beautifully for this bowl. Season lightly with salt and pepper.
04 - Divide the fluffed quinoa evenly between two serving bowls. Layer the sautéed vegetables over the quinoa. Top each bowl with a cooked egg, avocado slices, crumbled feta cheese, and a generous sprinkle of fresh parsley. Finish with freshly ground black pepper to taste.
05 - Serve immediately while warm for the best texture and flavor. Drizzle with hot sauce or sprinkle with chili flakes if desired.
