Soak the 4 slices of toast in 150 ml water mixed with 2 tablespoons instant broth for 2 minutes until soft. Add the egg and beat well, then season with ground pepper, tomato paste, mustard, and chives. Add the 500 g minced meat and knead for 1 minute until fully combined.
Melt 1 tablespoon butter in a small pan over medium heat. Add the finely chopped large onion and cook for 5 minutes until translucent. Stir this into the meat mixture and mix well.
Lightly grease a baking dish. Divide the meat mixture among the 200 g sliced cooked ham, then roll each slice up tightly with the seam facing down. Place the ham rolls seam-side down in the baking dish. Form any remaining meat into small balls and scatter around the rolls.
Place the baking dish on the stovetop over medium-high heat and fry the ham rolls for 3 minutes. Remove from heat and set aside.
Melt 1 tablespoon butter in a large pan over medium heat. Add the red pepper strips and fry for 2 minutes. Add the diced onion and cook for 4 minutes until soft. Add the washed and chopped fresh tomatoes, then the canned chopped tomatoes. Add oregano, tomato paste, cardamom, coriander, ginger powder, and lemongrass. Stir constantly for 1 minute (spices burn quickly).
Sprinkle 2 tablespoons flour over the sauce and stir for 1 minute. Pour in 250 ml water and the liquid from the canned tomatoes. Add 1 cup cream and bring to a boil, stirring frequently. Season with 1 tablespoon instant broth, hot paprika powder, ground pepper, and a dash of white wine.
Pour the sauce over the ham rolls and meatballs in the baking dish.
Preheat the oven to 200°C (392°F). Bake for 30 minutes until the meat is cooked through.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
