In a large bowl, add coleslaw mix, purple cabbage, onion, cilantro and green onions. toss to combine.
In a small bowl, prepare the coleslaw dressing. Add green onions, lime juice, olive oil, sugar/Splenda, salt and pepper. Whisk vigorously and allow it to rest for 2-3 minutes to allow the lime juice to mellow out the onions.
Pour dressing onto slaw mix, stir and cover. allow to rest in the refrigerator for 10 minutes. Stir again, and serve.
Notes
For this recipe, I used coleslaw mix that had green and red cabbage as well as shredded carrots. You can absolutely shred your a head of cabbage (either color) instead using a sharp knife or grater. You'll need roughly 3 total cups of packed, shredded cabbage.For extra lime flavor, add a bit of lime zest to the mix.Make it spicy with a few shakes of hot sauce, a pinch of red pepper flakes or 1/2 of a diced jalapeno pepper.
