Season the chicken breast with seasoning cube, Italian seasoning (or your choice), salt and pepper and mix.
Place a nonstick skillet or pot over medium heat and pour the oil into it.
Sear both sides of the chicken breast in the hot pan for a few minute, don't cook it fully because you're still going to continue the cooking later.
Place on a separate plate.
Add the chopped onion, minced ginger and saute, add salt and pepper and stir until the onion is soft and changes color.
In a small bowl, mix the brown sugar, ground mustard, dijon mustard, and mix.
Add the chicken broth with the mustard mixture and mix thoroughly.
Pour the mixture into the onion (in the pot) and bring it to boil.
Transfer the chicken breast and cook all together for about 5 minutes.
You will notice the water has been absorbed by the chicken and the sauce has been reduced.
For the salad:
Mix all the ingredients together and use any dressing of your choice. Slice the chicken and place on top of the salad.
You can adjust the sugar to your liking, if you don't like ground mustard use just dijon mustard, just make it yours.
