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.
