1. Warm up the cooking oil in a sizeable frying pan that won't stick on high heat. Add in the chicken and bell pepper, and continue stirring while cooking for 6-8 minutes until you confirm that the chicken is golden brown and fully cooked.
2. Lower the heat and include the spices, tomato paste, fruit purée, and a hint of salt. Mix in 2 tbsp of water until the sauce coats the meat evenly. Then, add the lime juice, and then take it off the heat.
3. Cook the white rice by following the directions on the packaging during this time. Combine the beans in a serving bowl after pouring the rice into it.
4. Set up bowls containing the soured cream (optional) and Gruyère. Put the chicken and peppers, rice mixture, lettuce, tortillas, and lime wedges on the table for your guests to enjoy (if desired).
