In a large glass bowl, add all the peppers, celery, carrot, onion. and cauliflower florets. Stir in salt and add enough water to cover vegetables. Cover bowl and refrigerate for 12 hours.
After 12 hours, drain and rinse vegetables to remove excess salt. Set bowl aside.
In a medium bowl.
Combine the garlic, oregano, red pepper flakes, celery seeds, and ground pepper. Pour in vinegar and whisk in olive oil until combined. Add this to the vegetable mixture, add in the chopped olives and toss well.
Place the vegetable mixture into jars making sure the vegetables are covered by the oil/vinegar blend. This recipe is good at 48 hours, however, the longer you let it ferment in the fridge the better the flavors are. I personally let it sit about a week.
