Bring a large pot of water with 1 teaspoon of salt to a boil. Set aside another large pot of water with ice and water.
Place the red onion in a colander and into the boiling water for 1-2 seconds and remove. Immediately dunk into iced water. Set aside. Add the rest of the vegetables into the hot water and leave them there for 10 seconds; remove them from the hot water. (pass them through a sieve if you don't have a large one to dunk all the veggies into). Immediately dunk them all into the iced water and again remove them from the iced water.
In a separate bowl place the herbs, vinegar, lime juice, water, salt, pepper and mix. Add cool heat shcoked vegetables and mix. Sprinkle olive oil and mix again. Refrigerate until ready to use. Up to 14 days.
