Melt a tablespoon of coconut oil in a large pan over a medium heat. Add the chicken and cook for about 5 minutes, stirring occasionally, until the chicken is cooked through. Remove the chicken and set aside.
Add a teaspoon of coconut oil to the pan and increase the heat to medium-high. Add the garlic, ginger, onion and chilli and stir-fry for about 3 minutes. Add the broccoli and pepper and stir-fry for another 3 minutes. Return the cooked chicken to the pan and add the noodles, soy sauce and lime juice. Stir well and cook for 3 minutes or until the chicken and noodles are heated through. Spoon the stir-fry into a warmed serving bowl. Sprinkle over the cashew nuts and mint and serve.
