If you buy whole squids, separate the head/tentacles from the tube. Cut the eyes and innards to only keep the tentacles. Remember to remove the beak from the tentacles.
Rinse the tubes, and remember to remove the cuttle (cuttlebone), which is a thin, clear sliver of cartilage.
Finely chop the tentacles to 1/8" pieces. Add the ground pork to the chopped tentacles. Mix the tentacle and pork by a constantly moving the knife up and down.
Once the tentacles and pork are thoroughly mixed, place the mixture to a mixing bowl. Add 2 tbsp white wine, 0.5 tsp salt, sprinkle some ground pepper, and mix thoroughly. Set the bowl aside.
Finely chop the pepper and onion
Place the sauce pan to the stove, turn heat to high, add 1 tbsp of olive oil, the chopped pepper, and 2/3 of the onion, and stir.
After about 3 minutes, add the tentacle/pork mixture, and stir to mix. Add the tomato paste, bayleaf, and ground pepper. Mix and simmer at medium heat to reduce for about 3-4 minutes. Pour the mixture to the mixing bowl, and cool it down.
Use a spoon to fill the tubes with the cooked mixture. Use a toothpick to seal the tubes openings. Finish all the tubes.
Put the sauce pan back onto the stove. Turn heat to high, add oil, and add the remaining chopped onion. Stir until the onion sweats. Add the diced tomato, paprika, wine, and remaining tentacle/pork if there is any. Stir to mix.
Place the stuffed tubes to the sauce. Heat to simmer. Turn heat to low. Cover the pan with a lid, and simmer at low heat for 25-30 mins.
If there is a lot of juice, remove the cooked tubes, and turn heat to high to reduce. Adjust the flavor with addition of salt or sugar.
