To begin rice, pour olive oil into a large wide saucepan and heat to medium high heat. Add diced onions and cover. Cook onions until translucent.
Add garlic, and stir. Then quickly add remaining marinade from Ziploc bag (you will cook this to a boil which kills all bacteria, however if you are worried about cooking the rice in the marinade, you can double it and use one portion to marinate the chicken, and set aside the other portion to cook with the rice).
Once you've added the marinade, continue cooking on medium high heat until boiling/bubbling for 2-3 minutes. This will kill any bacteria.
Add rice dry and sautee for 2-3 minutes, until rice has soaked up most of the marinade.
Add chicken broth and cover.
Cook until bubbling/boiling and then reduce heat to low. Just as you would with plain rice, cook on low until rice is done (it will take a little longer than normal rice because of all the additional ingredients). It should take about 25 minutes but look to see when the rice is done.
Once rice is done, fluff with a fork. Onions will settle to the top when rice is cooking. Mix the rice together.
Top rice with cooked chicken tenderloins/breasts. You can serve it just like this, or you can turn the oven on to low Broil, slice lemons and place on top of the rice and cook until lemons are slightly browned. These taste great squeezed over the dish.
Garnish with fresh parsley. Serve out of pan on the table. Squeeze lemon on top before eating. Enjoy!
