Start by rinsing your uncooked quinoa under cold water to remove its natural coating, which can taste bitter. Cook the quinoa according to the package instructions, usually about 15 minutes in boiling water, until fluffy. Set aside to cool.
Preheat your oven to 350°F (175°C) and line your baking pan with parchment paper for easy removal of the bars later.
In a large mixing bowl, combine the finely chopped macadamia nuts, unsweetened coconut flakes, drained chickpeas, dried pineapple, vanilla whey protein powder, and salt. Stir until all dry ingredients are evenly mixed.
In another bowl, whisk together the honey, coconut oil, egg white, and lime zest until well combined. This mixture will add moisture and sweetness to the bars.
Add the cooked quinoa to the dry ingredients and pour the wet mixture over the top. Fold everything together gently until well incorporated. Be careful not to overmix; you want to keep the texture.
Gently fold in the white chocolate chips, ensuring they’re evenly distributed throughout the mixture.
Transfer the mixture into the prepared baking pan, pressing it down firmly to create an even layer. Bake in the preheated oven for 20-25 minutes, until the edges are golden brown and the center is set.
Once baked, remove from the oven and let the bars cool in the pan for about 10 minutes. Lift the bars out using the parchment paper and let them cool completely on a wire rack. Once cooled, cut them into squares or rectangles.
