This is a meal by itself. To butterfly the chicken breast, place the breast flat onto a work surface, and with one hand on top to hold it in place, slice through the middle horizontally to cut almost in half and open out flat. To peel and chop a lemon, cut a slice from the top and the bottom of the fruit. Cut away the rind, pith and skin, working from top to bottom, following the curve of the fruit. Slice the peeled fruit crosswise into 1/4 inch slices and then stack and chop the slices finely. Please note, cooking time indicated includes marinating time and roasting time of garlic for garlic mayo.
