Sauté Peppers: Heat 1 tablespoon olive oil in a large pot over medium heat. Add the tri-pepper mix and cook for about 2 to 3 minutes, stirring occasionally, until slightly softened.
Add Garlic: Stir in 1 tablespoon chopped garlic and cook for about 30 seconds, just until fragrant.
Toast Rice and Spices: Add the white rice, 1 teaspoon cumin, ½ teaspoon crushed red pepper, and 1 teaspoon kosher salt. Stir well and cook for about 1 minute to lightly toast the rice and spices.
Add Chicken Stock: Pour in the chicken stock and stir to combine. Bring the mixture to a gentle simmer.
Cook Rice: Reduce the heat to low and cover the pot. Cook for about 15 to 18 minutes, or until the rice is tender and the chicken stock has been absorbed.
Make Verde Cream: While the rice cooks, add 1 cup cilantro and 3 green onions to a food processor. Pour in the heavy whipping cream and process until smooth and pale green.
Prepare Garnishes: Chop the remaining ¼ cup cilantro and thinly slice the remaining 2 green onions. Set them aside for serving.
Season Shrimp: In a large bowl, combine 1 teaspoon cumin, ½ teaspoon crushed red pepper, 1 teaspoon kosher salt, and ½ teaspoon black pepper. Add the shrimp and toss until evenly coated.
Heat Skillet: Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
Cook Garlic: Add 1 tablespoon chopped garlic and cook for about 30 seconds, stirring constantly so it does not burn.
Cook Shrimp: Add the seasoned shrimp to the skillet and cook for about 1 to 2 minutes, stirring occasionally.
Add Verde Cream: Reduce the heat to medium and pour the cilantro cream mixture over the shrimp. Stir well and gently simmer for about 3 to 4 minutes, or until the shrimp are opaque and cooked through and the sauce is hot and creamy.
Finish Spiced Rice: Add the cooked black beans to the finished rice and gently stir until evenly combined. Cook over low heat for another 1 to 2 minutes, if needed, until the beans are heated through.
Plate and Serve: Spoon the spiced rice and black beans onto plates. Top with the creamy shrimp verde and spoon additional sauce over each serving.
Garnish: Finish with the chopped cilantro and sliced green onions. Serve immediately.
