preserving peppers

 one HUGE box of organic green peppers ( approx 300 :->) generously given to us by a friend
 We managed to used some  but after a few days of very hot weather, I decided, it`s time to preserve the rest.... somehow.. :)
  Washed and sliced, we dehydrated a large part and  froze all the rest -stir fried  with olive oil and garlic
