In a clean sink, filled with water, add greens. Thoroughly wash any dirt/grit. Drain. Remove tough stems, roll 4-6 leaves at a time, and chop into 1 inch pieces. Place back into sink.
In a large dutch oven, bring 2 cans (4 cups) broth to a boil, add ham hocks, onion, garlic, hot sauce, vinegar, 1/4 c sugar, and seasoning. Lower heat, Cover and simmer 1 hr 30 mins (make sure that the liquid covers half the ham hock, if not add additional chicken broth).
Add greens. When greens have reduced down, add the remaining 1/4 c sugar. Toss to combine. Cover and cook for another 1 hr 30 mins - 2 hours. If the ham hocks have not shredded, remove, chop and return to pan.
