Place a large skillet over medium heat and add olive oil. Saute onion, bacon, and mushrooms 2 minutes or until onions start becoming tender. Add in garlic and stir until fragrant; about 30 seconds.
Pour in frozen brown rice, frozen vegetables, and edamame. Increase heat to high and stir fry until completely warmed through. Reduce heat to medium.
Push rice mixture to one side of the pan and scramble the egg whites on the empty side of the pan. Once they are scrambled to your liking, stir into the rice and toss with soy sauce, sesame oil, and pepper. Stir briefly and serve hot.
