Sauté the onion and garlic in a large skillet over medium high heat until softened, about 5 minutes. Add bacon or ham and cook until it begins to brown along the edges, about 3 minutes. Stir in greens, salt, and pepper.
Stir the greens over high heat for a couple minutes until beginning to wilt, then add broth and bring to a boil. Cover pan and reduce heat to extra low.
5 minutes later stir greens – they may be done depending on their freshness , but if they aren’t, return the lid and continue cooking until desired doneness. Season with salt and lots of pepper! Serve over brown rice if desired.
