Chop the onions, garlic, celery and pimento peppers (seasoning pepper) and add to chive, big leaf thyme, chadon beni and spanish thyme.
Add some of the ingredients, ½ cup of water and about ¼ cup of vinegar in the blender.
Note: Add handfuls of the ingredients at a time and make sure the blender's cover is tightly secured. The ingredients will have to be blended in batches! You may add the hot pepper at this step if desired.
Blend until smooth. Strain the green seasoning mixture and collect the liquid below. The liquid will be reused to blend the other batches of ingredients.
Collect the strained mixture in a separate bowl.
When all the ingredients have been blended pour everything, liquid also, into a bowl and add salt to taste. Store in containers and refrigerate.
