user14580: Do any of the Buddhist texts mention anything about Zoroastrianism?
Has the Buddha ever met Zoroaster?

user471: There is no known mention of Zoroastrianism or Zoroaster in Buddhist texts, as far as I know, but there is a mention of "Gotama" in a Zoroastrian text.
According to a letter published in 1898 (from here), the reference to Gotama in a Zoroastrian text likely refers to the Vedic sage Gautama Maharishi, and not Gautama Buddha.
From the letter:

I am able to discover an important identification of the Avestic
  Gaotema with the Vedic Gotama. In the Rig-veda, Nodhas is Gotama's
  son, who is called Naidhyangho  Gaotemahe in the Avesta. Hence it is
  probable that the controversies  referred to in the Farvardin Yasht
  was carried on by Zoroastrians against the Vedic poet Nodhas, and not
  against Gaotama Buddha.
... The  Avesta  text  runs  thus:— "Through
  their brightness and glory a man is born  who is a chief in assemblies
  and meetings, who listens well to the holy words, who wishes for
  wisdom, and who returns a victor from discussions with Gaotema,  the 
  heretic." ...  Now  there  are  two  Gotamas  who  are  principally
  familiar to us in the Vedic and the Buddhistic literature. One is
  Rishi Gotama and the other Gotama Buddha. The latter is very well
  known to us as  the  founder  of  Buddhism. The  former is one of the
  seven rishis or sages mentioned in the Rig-veda.

Zoroaster seems to have lived before the time of the Buddha, far away in Persia, so it is unlikely that they have met each other. There is also no known record of that, as far as I know.
According to this Wikipedia page, there was some persecution against Buddhists in Persia and Afghanistan by the Sassanids after Zoroastrianism became the official religion of Persia in 224 CE. Apart from this, I am not aware of other Buddhist-Zoroastrian encounters.

user-1: Do any of the Buddhist texts mention anything about Zoroastrianism?
At the time of the Buddha the Indian spiritual scenario was under heavy influence of vedic brahminism which was on the west of Buddha's kingdom. 
It is highly unlikely that Zoroastrianism which lay further west of Indus valley would cross the valley and influence Buddhist monks to get an honourable mention.
Also, it was only after the invasion of Alexander the Great that Indians came in heavy contact of Persia through the Satarps of Alexander. And his conquest was some 200 years after the Buddha. So it is unlikely that the Buddha himself would have encountered any human from Persia to tell him about Zoroastrianism as He met Jainas and Vedic brahmins.
Buddhist geography in the scriptures does not mention anything in the west not even Egypt.
Has the Buddha ever met Zoroaster?
Zoraster was hundreds or thousands of years prior to Gautama the Buddha so they might not have met in person.
But the Buddha is known to have a council with Gods and He was also possesor of super natural powers. So may be they would have had a chat in some different realms. But that only a Buddha can confirm for you.
