What you always needs to have at home while in the first phase is >70% chocolate. Since you cut out all the sugar and sweetening you 'll need something if you get a craving - just a small piece though...
At evenings if I'm in the mood for something to eat, more luxurious, here's some tips:
* different cheese (brie, white/blue cheese) and finn crisp (or other fiber cracker with no sweetening)
* whipped cream, fresh berrys (straw-, rasp-, blue-berries) perhaps with some >70% chocolate splinter
* sliced apple with cinnamon in the micro until warm and mushy, served with lightly whipped cream and chopped almonds
* fruit salad (apple, pear, orange), whipped cream
* a handfull of nuts
