1. In a medium pot on the stove, heat the stock with the kaffir lime leaves, ginger, and fish sauce. Bring to a boil, then turn off heat to conserve energy and let steep for 20 minutes. Remove and discard the limes leaves and the ginger.
2. Turn the heat to medium and add the carrots, peppers, green onion tops, and coconut milk to the stock. Cook for 5 minutes, until the vegetables are tender. Add the chicken pieces and cook for another few minutes, until the chicken is tender and cooked through.
3. Add the rice noodles and take the pot off the heat, again to conserve energy. Cover the pot and allow the noodles to soften (which will take 10-15 minutes). When noodles are cooked through, portion the soup ingredients evenly into bowls. Top each portion with cilantro and mint. Squeeze fresh lime over each bowl before serving, and add more tamarind-date or chile sauce to taste.
