Bring water to boil. Add salt until it taste like the sea. (approximately a tablespoon per quart of water.) Cook until tender - approximately 9 to 1o minutes. Drain and add to vegetables while still warm. They will absorb the vinaigrette if still warm.
Small dice all vegetables. I place my shallot in cold water to rinse the strong taste from them, drain, and dry them on a paper towel, then put them in the vinegar to keep them from oxidizing.
Mix vinegar, shallot/onion, mustard in a bowl. Add vegetables. Add oil. Add pasta. Add herbs. Adjust seasonings.
