CHICKEN PHO BONE BROTH SOUP

I have spent a long time perfecting this recipe. This is my 3 year old's favorite soup. She loves to drink it plain from a mug! Charring the onion and ginger brings out the sweetness. If using an open flame it only needs about 20-30 seconds on each side. If you're broiling, probably no more than 4-5 minutes on each side.

This is a "Pho" based broth, but don't limit yourself on what you can add in. Even though you may be tempted to add hoisin and siracha, the flavor is so concentrated and delicate that hoisin and siracha overpower it. Enjoy!
