In a large pot, heat olive oil over medium-high heat.
Add chicken parts and sausage and cook, stirring occasionally, until lightly browned, about 5-10 minutes remove meat from pot set aside.
Reduce heat to medium add onions, garlic, parsley, red bell pepper,tomatoes, and season with salt and pepper. Cook, stirring occasionally, until soft, about 15 minutes, until liquid from the tomatoes thickens, add sausage bay leaves and datil pepper halves and cook about 5 minutes. Stir in chicken parts, rice, chicken broth. Bring to a boil, reduce heat to low, and simmer covered, until rice is cooked through, about 35-45 minutes stir gently every few minutes.
With about 10 minutes to go stir in the shrimp and scallions, uncover and turn up the heat to medium until shrimp is pink.
Before serving remove the datil peppers halves. Guess will not enjoy biting into these peppers.
