Using a sharp knife, peel the citrus fruits; be sure to remove all of the bitter white pith. Working over a strainer set in a bowl, cut in between the membranes to release the citrus sections into the strainer. Squeeze the juice from the membranes into the strainer.
Measure 2 tablespoons of the strained juice into a bowl; drink the rest. Whisk the olive oil into the juice; season with salt and pepper. Add the arugula, mint and red onion and toss. Add the fruit, toss gently and serve.
