In a mixing bowl, combine the jerk seasoning with the shrimp and flank steak, ensuring each piece is generously coated. Cover and let it marinate for at least 30 minutes to allow the spices to penetrate deeply.
In a medium saucepan over medium heat, warm 1 tablespoon of olive oil. Add the diced onion, bell pepper, and minced garlic. Sauté until the vegetables soften and become fragrant—about 3-4 minutes. Stir in the yellow rice, coating it with the oil and vegetables. Pour in the chicken broth and bring to a boil. Reduce the heat to low, cover, and simmer for 15-20 minutes, or until the rice is tender and the liquid is absorbed.
Heat a large skillet over medium-high heat and add 1 tablespoon olive oil. Once hot, add the marinated steak. Sear for about 4-5 minutes per side, depending on thickness, until it reaches your desired doneness. Remove from the skillet and let it rest for a few minutes before slicing thinly against the grain.
In the same skillet, add the shrimp and cook for 2-3 minutes on each side until they turn pink and opaque. Avoid overcooking to keep them tender.
Fluff the yellow rice with a fork and spread it evenly on serving plates. Arrange sliced flank steak and cooked shrimp on top. Garnish with chopped green onions for a fresh, vibrant finish.
