Marinade the chicken in all the ingredients under the chicken list.
Heat the oil in a large pan, over medium high heat and add the chicken. Brown on each side for 2-3 minutes. Remove the chicken and marinade leaving about 2 tbsp marinade in the pan. Set aside.
Stir flour into the pan and whisk in. Add the onions and cook over a low heat for 3-4 minutes.
