De-stem and chop the collard greens. An easy way to de-stem collard greens is by folding them in half lengthwise along the stem with the darker green side down and then pull up the stem until it comes off and you’re left mostly with leaf. An easy way to chop the collards is to stack a few leaves, roll them up into a cigar shape and cut the through the collard cylinder, making strips.
Place strips in a large bowl. Pour olive oil on collard strips and sprinkle on salt. Massage the oil and salt into the strips with your hands until all pieces are well coated.
Whisk together apple cider vinegar, sun-dried tomatoes, onions, garlic, red pepper flakes and ground pepper.
Pour apple cider vinegar dressing over the collard green strips. Let marinate in the refrigerator for at least 3-4 hours, but overnight is best.
