In a large skillet, heat the olive oil over medium heat until shimmering. Add the finely chopped onion and diced green bell pepper, sautéing for about 5 minutes, or until the vegetables are softened and translucent.
Add the minced garlic to the skillet and cook for an additional minute, stirring frequently until fragrant and aromatic.
Introduce the ground chicken to the skillet, using a wooden spoon to break it apart as it cooks. Continue cooking for approximately 6-8 minutes, or until the chicken is browned and fully cooked through.
Sprinkle the Cajun seasoning and smoked paprika over the browned chicken, stirring vigorously to ensure the chicken is evenly coated with the spices.
Pour in the crushed tomatoes, tomato paste, and Worcestershire sauce. Stir thoroughly to combine all ingredients, allowing the sauces to meld into the mixture.
Lower the heat to a gentle simmer and let the mixture cook for about 10-15 minutes. This allows the flavors to develop harmoniously. Taste the mixture and adjust seasoning with salt and pepper as needed.
Meanwhile, toast the hamburger buns lightly either in a skillet until golden or in a toaster, ensuring a crispy texture.
Once the filling is ready, generously spoon the Cajun chicken mixture onto the bottom half of each toasted bun. Cap each with the top half of the bun to create your delicious sandwich.
