The day prior, cut each breast in half across the width of the breast.
Place chicken in bowl and pour fish sauce over. Toss to coat.
Remove 3 inches of dark green part of scallions and discard.
Slice scallions very thin, on the bias, about 1/8 inch thick.
Add scallions to bowl with chicken and toss.
Cover and chill for 18-24 hours.
Preheat oven to 500°.
Lift chicken from fish sauce, letting scallion slices remain on the chicken.
Place chicken on rimmed baking sheet.
Bake 10-12 minutes, until just firm, then put under broiler about 8 inches from heat for 1 to 2 minutes, until golden.
Remove from oven, remove skin and serve immediately, if serving hot.
