So if I say "Je prends le train a la lycée. " this is correct ?

Why pieces en chocolat instead of pieces au Chocolat?  I always thought the principal ingredient of a food used "a la" or "au"..

I have a couple of related questions about a couple of the passages that could be potentially confusing or misleading. 

First, "et mélangez-la avec l'oignon et l'ail finement hachés," ... it's clear in writing, but not necessarily in speech, that "finely chopped" refers to both the onion & the garlic.

Secondly, "le thym, le persil, l'ognon pays et une pincée de sel et de poivre.": I looked this up on the web, & apparently the "pinch of" refers to both the salt and the pepper. So, how do you know that? Because, would "a pinch of salt & some pepper" be expressed "une pincée de sel et du poivre"?

The passage in question is, "pour que votre repas soit un succès !" I couldn't hear the "pour" at all despite running the audio track several times. 

In the last sentence, in the passage " rappelle-moi dès que tu trouveras le temps de parler" I didn't hear the "dès" at all, even after listening several times. Is this just how the French (or Parisians specifically) talk all the time?

My question is about the use of 'en' here. Does this sentence refer to something previously mentioned, the subject from which the speaker wants to benefit? Is it connected to the use of 'de' with vouloir?
