In a medium-sized glass or metal mixing bowl, combine the tuna, cooked vegetables, mayonnaise, spicy sauce (if using), chopped parsley and cilantro, and the juice of one lime. Mix well, adding salt and pepper to taste. Stir gently with a wooden spoon or rubber scraper, folding the ingredients in rather than beating.
Cut the avocados lengthwise, remove the seeds, and calmly and carefully remove the skin. Squeeze the juice of the other two limes over all the surfaces of the avocado flesh to prevent it from darkening.
Place each avocado half on a salad plate. If necessary, cut a small slice from the bottom of each half so it can stand upright. Fill the avocados with the tuna mixture. Sprinkle with more cilantro or chopped parsley, if desired. Serve immediately or chill briefly before serving.
