Rinse the dry quinoa under cold water using a fine-mesh strainer.
In a small saucepan, combine the quinoa and water then bring to a boil.
Reduce heat to low, cover, and simmer for 15 minutes or until the water is absorbed.
While the quinoa cooks, dice the chicken breast into small, uniform bite-sized pieces.
Heat the olive oil in a large skillet over medium heat and sauté the chicken until golden and cooked through.
Add the minced garlic and frozen peas to the skillet, stirring for 2 minutes until the peas are tender and fragrant.
Fluff the cooked quinoa with a fork and add it to the skillet with the chicken and peas.
Stir in the lemon juice, lemon zest, sea salt, and black pepper until well combined.
Remove the skillet from heat and stir in the chopped fresh parsley before serving warm.
