Cook rice according to package instructions. Keep warm.
Make curry sauce. Place coconut milk, curry, honey, soy sauce, and salt in a saucepan. Whisk until smooth. Heat over medium-high until bubbling, reduce heat to medium, and simmer 5 minutes. Remove from heat. Stir in lime juice and herbs. Let stand 10 minutes. Remove herbs.
Sauté shrimp and vegetables. Heat oil over medium-high in a large skillet until it shimmers.* Add garlic and onion; cook until softened, stirring occasionally, about 2 minutes. Add bell pepper; cook 1 minute or until slightly softened. Add cauliflower, shrimp, and salt. Cook, stirring occasionally until shrimp are almost opaque.
Finish curry sauce and pour over shrimp and veggies. Add 2 cups coconut curry sauce; bring to a simmer. Cook 2 minutes. Stir in kale. Cook until shrimp are done, kale is wilted, and cauliflower is tender.
Garnish and enjoy! Remove curry mixture from heat. Squeeze a lime over the top and garnish with radishes and torn herbs. Spoon rice into wide bowls. Top with curry mixture and sprinkle with chopped nuts
