We made this last week and it was 5 minutes to prep and very delicious. We used thighs (had them in the freezer) and I would add a bit more lemon. We ate it over noodles the first night and then used the leftovers to make sandwiches (it was like pulled pork except of course not pork).

Place chicken breasts, Italian dressing mix, butter, lemon juice &
