Cook quinoa according to package instructions and allow it to cool.
Rinse and drain 1 can of brown lentils or your preferred legume.
Dice 1 avocado into chunks.
Thinly slice 1/4 of a red onion.
In a large mixing bowl, combine the cooked quinoa, brown lentils, sliced oranges, diced avocado, and sliced red onion. Gently toss the ingredients together to mix evenly.
In a small bowl or mason jar, whisk together the zests and juice of orange (1/2 cup) and lime. Add 1 tbsp of Dijon mustard, and 1-2 tbsp of maple syrup. Mix until well combined to create the vinaigrette.
Garnish with additional citrus zest, fresh herbs like cilantro or parsley, and/or toasted nuts or seeds for extra flavor and texture.
Serve immediately and enjoy your refreshing and nutritious citrus quinoa-lentil salad!
