An already written marketing plan about a food product like a burrito or meat pie.

I'd be a bit more specific as to your objective.  Are you looking
to start up a company, sell an existing product, develop
an existing product, build its brand or all of the above.
Depending on where you are and what channels you are
looking to distribute to, you may or may not get the right answer.
Some questions that might help the researchers:
Is it a single item or a brand that you are selling?
Is your objective wholesale or retail?
Which retail is your target?  C-Stores, Grocery, Fast Food?
Why does a meat pie interest you?  Similar product.

Just some food (haha) for thought.  Best of luck on your venture.

Hi, thank-you for asking this. 
I am currently writing a marketing plan for a product that is similar
to a meat pie or it is a pastry dough filled with meat.
We are selling these wholesale to specialty stores and grocery stores.
I was thinking that I wanted to see an already established marketing
plan for a similar product.

Thanks

Expect it will be hard for the researchers, and 
I would focus on your channels and what
products are similar.  Example, if I was going to
sell a meat pie to Specialty and Grocery, I
might first look at all the products that are
sold to these, get any plans I could then see
which ones might best give me the ideas I
was looking for.  I could have a Marketing
Plan for a meat pie, but it might not be any 
good or useful for your purposes.  Better to
throw out a wide net.  Hope your products are
pasteis from Brazi, I miss them.  Good luck.

Also, just in case you live near a BSchool, students
are great people to do work like this (write up a plan,
not search for one).  And they are usually free.
