Prepare iced ginger tea: Bring water to a simmer, remove from heat, and steep tea bags for 10 minutes. Sweeten with sugar or honey. Cool, refrigerate, and serve over ice.
Cook rice: Rinse thoroughly. Cook according to package instructions. Season with salt and pepper, cover, and keep warm.
Prep all ingredients per the instructions above.
Make curry: Heat olive oil in a pot over medium-low heat. Sauté onion until softened. Add chicken and cook for 1–2 minutes. Stir in ginger, garlic, and curry powder; sauté 3 minutes. Pour in 3/4 of the coconut milk. Mix cornstarch with reserved coconut milk and add. Bring to a boil, then simmer until chicken reaches 165°F (74°C). Stir in fish sauce (if using), brown sugar, and lime juice. Simmer for 5 minutes. Garnish with cilantro.
Prepare spring rolls: Soften one rice paper sheet at a time in warm water. Lay flat on a towel. Layer with lettuce, carrot, cucumber, jalapeño, scallions, mint, and cilantro. Fold sides over, then roll tightly. Repeat with remaining sheets.
Make peanut sauce: Mix peanut butter, rice vinegar, soy sauce, honey, sesame oil, and garlic. Add water gradually until smooth and creamy.
Serve the curry with rice, alongside spring rolls with peanut sauce and iced ginger tea.
