Remove kale leaves from stems (see note for help).
Stack kale leaves and roll up. Slice about ¼-inch thick.
Add sliced kale to a large bowl. Toss with 1 tbsp. olive oil and ½ tsp. salt. Set aside while you prepare the remaining salad ingredients.
Prepare Vinaigrette:
In a small bowl, combine lime juice, apple cider vinegar, cayenne, ancho chili pepper powder, maple syrup, olive oil, salt, and pepper.
Whisk ingredients together.
Taste vinaigrette and add more salt, if necessary. Set aside.
Finish salad:
Pour vinaigrette over kale.
Take a minute to massage vinaigrette into kale, using your hands.
Top kale with cherry tomatoes, black beans, cilantro, and corn. Toss to combine.
Add avocado and feta cheese to salad. Fold in gently.
Serve salad topped with tortilla chips (optional).
Notes
To remove tough stems from kale leaves, grab onto top of stem and quickly slide your hand down, separating leaves from stem as you go.If you can't find ancho chili pepper powder (I got it at Penzeys), replace it with regular chili powder.
