Generously season the ground lamb with salt and pepper. Combine the tomato paste and water in a bowl. Add the crushed tomatoes and whisk together.
Heat a large pan over medium-high. Add the duck bacon and cook until just cooked. Toss in the garlic and cook for about a minute. Add the onion and bell peppers. Cook until the onions are translucent. Add the ground lamb and cook until it starts to brown.
Once the lamb has browned, add the red pepper flakes, sugar, oregano and basil. Add the red wine and let it reduce by half.
Finally, add the tomato mixture. Reduce the heat to low, cover, and simmer for at least 30 minutes. Toss the pasta in the sauce and serve.
