Wash the chops, pat them dry and put them in a roaster. Drain the pineapple and cut into pieces. Peel onion and slice into fine rings. Spread onion and pineapple on the meat.
Drain the tomato peppers on a sieve, puree and mix with ketchup. Season vigorously with salt, pepper and paprika. Spread the sauce over the meat and braise in a preheated oven (electric cooker: 200 °C/ gas: level 3) for approx. 2 hours with the lid closed.
30 minutes before the end of the cooking time, remove the lid and braise open. Garnish with basil and serve.
