Mix the Cajun seasoning spices in a small bowl until combined.
Add the chicken, 1 tablespoon of olive oil, and the cajun seasoning blend to a large bowl. Mix until each piece is thoroughly coated.
Heat a deep skillet or Dutch oven over medium heat with 2 tablespoons of olive oil and a tablespoon of butter. Add the seasoned chicken pieces.
Cook on each side for 3-4 minutes until browned but not cooked through (it'll finish cooking later). Remove the chicken from the skillet and set aside.
In the same pot, add the diced onion, bell pepper, and minced garlic. Cook for 2-3 minutes stirring occasionally until softened. Stir in the tomato paste.
Add in the dry orzo and chicken broth. Stir to combine then nestle the partially cooked chicken back in. Bring to a boil over medium-high heat. Reduce to a simmer over low heat. Stir occasionally until the orzo is al dente and the chicken is tender, about 9-11 minutes.
Turn off the heat. Stir in the coconut cream (or milk of choice), and fresh lemon juice. Season to taste with kosher salt and freshly ground black pepper. Garnish with fresh herbs if desired.
