If you prefer, you can juice the lime and add to taste with the salt/pepper.
Consider some chili oil for a bit of kick on the garnish as well.
Note: Don't over roast your parsnips by forgetting about them in the oven like I did when I made a patch to take the photo... I kind of forgot about them until we realized it was almost burnt. The soups much better with a lighter roast!
Its OK if you're not perfect cooking sometime, you can always learn... like I learned that I really just need to set timers when roasting things and getting other work done!
