If you can do this, would you need to provide both the values in order for this to pass through an if else statement?

No, variables as you are describing can only have one value... What you are looking for is an Array. Have a look at this StackOverflow Thread
Keep Coding! :)

Now for example, you could put those to values into an array variable like this:
var pickles = ['green', 'vegetable'];
--- The rest of this is not directly related to your question. ---
I tried your assignment on codepen and it surprised me. I figured that since you were doing a boolean operation (&&) the result would be the logical AND of the "truthiness" of the two strings. I know that a string is usually considered "truthy" if it is not empty or null, so I was expecting the value to be true. Instead, codepen said the value was vegetable!
So I looked up the logical operators at MDN and discovered that "Logical AND (expr1 && expr2) Returns expr1 if it can be converted to false; otherwise, returns expr2." So it made sense, as "green" would evaulate as "true", your assignment gets "vegetable".
Anyway, by looking into your question, I learned something about JavaScript logical operators I didn't know!
