Split List By Value and Keep Separators

I have a list called list_of_strings that looks like this:

['a', 'b', 'c', 'a', 'd', 'c', 'e']

I want to split this list by a value (in this case c). I also want to keep c in the resulting split.

So the expected result is:

[['a', 'b', 'c'], ['a', 'd', 'c'], ['e']]]

Any easy way to do this?
