Cook rice noodles according to package directions.
Heat coconut oil in a large skillet or wok over medium heat. Add bell pepper and broccoli and cook for 5 minutes, or until slightly tender.
Stir in coconut milk, red curry paste, soy sauce, lime juice, and brown sugar. Bring to a simmer and cook for 5 minutes, stirring occasionally, until the sauce has thickened slightly.
Add cooked noodles to the skillet and toss to coat. Serve immediately, garnished with chopped cilantro.
Notes
Feel free to add protein of your choice such as tofu, chicken, or shrimp. Adjust the amount of red curry paste to your preference.
