Spray a large nonstick fry pan with cooking spray and brown chicken at med-high.
Chop onion (finely) and add only half of the chopped onion to the pan as you cut. Add garlic and sauté about 1 minute.
Add broth and spices to browned chicken and stir. Bring to a boil and partially cover. Reduce heat to a med-low for a high simmer. Turn often to have the sauce absorb on both sides (this does not make a sauce, just moist saucy chicken pieces).
In the meantime…
Add remaining chopped onion.
Finely chop celery, adding to pan as you cut. Add cold cooked rice, soy sauce, curry and fresh pepper.
Crush bouillon cube and add to pan. Toss until mixture is combined and heated through.
Place broccoli in a large microwave safe dish with a lid.
Cook at high for five minutes. Let stand.
Stir and reheat broccoli until chicken and rice are ready to serve.
