Place bacon on paper towel-lined plate and microwave on High until crisp, about 4 minutes. Cut into 1-inch pieces.
In 5- to 6-quart slow cooker, whisk together chicken broth, white wine. and tomato paste. Add garlic, onion, and tomatoes and mix to combine. Fold in pork, bacon, and thyme.
Cook, covered, until pork easily pulls apart, 5 to 6 hours on High or 7 to 8 hours on Low.
Thirty-five minutes before serving, discard thyme, then gently stir in lentils. With slow cooker on High, cover and continue cooking until lentils are just tender, 30 to 35 minutes. Gently fold in beans and cook until heated through, about 3 minutes. Serve with crusty bread if desired.
