Alternative for the phrase "in a word"

I have the following sentence:

So, in a word, my goal is to eat Kentucky Fried Chicken.

I have read elsewhere that using the phrase "in a word" here is not best practice - because I have an entire clause after it.

What would be an alternative way to say what I'm trying to get across? I am trying to say that if I had to write it down or describe it, then this is my goal.

Thanks in advance!

Solution 1:

If you want an idiomatic expression you may use:

In a nutshell:

You can use in a nutshell to indicate that you are saying something in a very brief way, using few words.

• In a nutshell, the owners thought they knew best. This, in a nutshell, is what Richard Chaplin appears to have done.

Solution 2:

You could use "in short"

So, in short, my goal is to eat Kentucky Fried Chicken.

Do not, however, take the meaning of "in a word" literally. Your example is fine as it is.
