Cut the ends off the onion, remove peel
Pop out the centre of the onion, discard centre bit
Prepare a good amount of tin foil
Combine minced garlic and whatever else you think would be good with the Greek yogurt. I'm also including minced ginger root and chopped parsley.
All mixed into a nice paste
Fill the onion hole with your mixture, there should be more left after filling
Use the rest of the mix to coat the onion
I love seasonings, so I seasoned all over the top of the mix. I also put some olive oil in the tin foil.
Here's the onion package on the grill (and some chicken as well)
And the final onion, it's not much to look at but it's delicious. Enjoy!
