How to Make It
In a large pot, heat the olive oil. Add the bacon and cook over high heat until browned, about 6 minutes. Add the onion and garlic and cook over moderate heat, stirring occasionally, until softened, about 6 minutes.
Add the greens, season with salt and pepper and toss to wilt slightly. Stir in the peppers, water and vinegar, cover and cook over low heat, stirring occasionally, until the greens are tender, 10 to 15 minutes. Transfer to a bowl and serve.
