In a large saucepan, heat coconut water over medium heat until steaming. Toss in Thai basil leaves, sugar snap peas, red onion, and sambal/chili paste before simmering for 10 minutes while stirring intermittently. Add in sesame oil and sliced red chilies for extra flavor, then stir in palm sugar or brown sugar and fish sauce. Keep simmering for an additional 5 minutes, stirring occasionally.
