Combine coleslaw mix, diced mango, green onions, cilantro, and bell pepper in a large bowl; stir gently to combine.
1 bag (8 ounces) coleslaw mix, 2 large mangos, diced small, 3 green onions, thinly sliced, ½ cup minced fresh cilantro, ½ red bell pepper, cut into thin short strips
In a small bowl, whisk together lime juice, oil, honey, chili powder, and salt until blended.
2 tablespoons fresh lime juice, 2 tablespoons oil, 1 teaspoon honey or agave syrup, ½ teaspoon chili powder, more if desired, ¼ teaspoon kosher salt
Add dressing to salad; stir well until combined.
For best flavor, chill mango slaw for 1 hour to let flavors meld but it can be served immediately, if you prefer. Serve mango slaw as a topping for tacos (it's especially good on fish tacos) or as a side salad.
Notes
Add-ins: Add 1 jalapeño pepper, minced. Leave the seeds and ribs in for even more heat. If you like, add the zest of the lime to the dressing (be sure to zest the lime before juicing it). Finely diced pineapple or avocado can be added. If you want to add cheese, try queso fresco or cotija.
Storage: Leftover slaw can be refrigerated for up to 3 days. Stir before serving.
