In a large pot, heat a small amount of oil over medium heat. Add the beef shank, pork ribs or belly, and chicken pieces. Cook until browned on all sides. Remove the meat and set aside.
In the same pot, add the sliced chorizo sausage and cook for a few minutes until it starts to release its oil. Add the finely chopped onion and minced garlic, and sauté until soft and translucent.
Add the chopped potatoes, carrots, leek, and cabbage to the pot. Stir in the paprika, ground black pepper, and salt. Cook for about 5 minutes, stirring occasionally.
Return the browned meat to the pot. Add the soaked chickpeas and white beans. Pour in the water or beef broth and add the bay leaf. Bring to a boil, then reduce the heat and let it simmer for about 1.5 to 2 hours, or until the meat and beans are tender.
Stir in the rice and small pasta. Continue to cook for another 15-20 minutes, or until the rice and pasta are cooked.
Remove the bay leaf before serving. Ladle the escudella into bowls and garnish with freshly chopped parsley. Serve hot with crusty bread.
Enjoy your meal!
