1.
Heat 1 tablespoon oil in heavy extra-large pot over medium-high heat. Add ham; sauté until browned, about 10 minutes. Transfer to bowl and reserve.

Sauté until onions wilt, about 2 minutes. Reduce heat to medium-low. Add filé powder, oregano, and cayenne pepper. Stir 3 minutes. Add collard greens, mustard greens, watercress, spinach, and sugar. Toss to combine. Add 2 cups broth. Cover and cook until all greens are tender, stirring occasionally, about 15 minutes. Remove pot from heat.

Working in batches of 2 cups, puree greens in processor, scraping down sides occasionally. Transfer puree to bowl.
