Cook rice according to package directions.
Heat the olive oil in a large skillet or wok over medium heat. Add the onion, bell peppers, and zucchini and cook until softened, about 5 minutes.
Add the frozen brown rice to the skillet and stir to combine. Cook until the rice is heated through, about 2 minutes.
In a small bowl, whisk together the coconut milk, soy sauce, lime juice, sweet chili sauce, brown sugar, red curry paste, dried garlic, and dried basil.
Pour the sauce into the skillet and stir to combine. Bring the mixture to a boil, then reduce the heat to low and simmer for 10 minutes, or until the sauce has thickened and the vegetables are tender.
Remove the skillet from the heat and stir in the fresh basil.
Serve immediately and enjoy!
