Season chicken generously with salt and pepper. Slice 1 lemon into 1/8- to 1/4-inch slices. Place chicken in zipper-lock bags or vacuum bags and add whole roughly chopped scallions and ginger. Remove air from zipper-lock bags by closing the bags, leaving the last inch of the top un-sealed. Slowly lower into a pot of water, sealing the bag completely just before it fully submerges. If using a vacuum bag, seal according to manufacturer instructions.
