Peel 2 of the oranges and peel the fruit apart so the individual sections separate. Remove the membrane and seeds from the jalapeno and slice the flesh into thin strips. Rough chop the cilantro. Add everything to a large bowl with the coleslaw mix.
Over a small bowl, juice and zest the lime and the remaining mandarin orange. Whisk in the EVOO, salt and pepper.
Pour dressing over the coleslaw mix, gently toss and serve.
