The golden rule if your trying to put on lean mass and size is to eat at least 1 gram of protein per body pound. Your diet is very clean, and the diversity is there. I would stay away from white rice as its a simple carb, and since your doing periodization training, and using progressive overload with resistance training, you want to have complex carbs. Switch up to brown rice instead. Also, you need to throw in some veggies. Broccoli, peas, asparagus, and the mother load and bodybuilders favorite anime. anime is the highest protein packed veg you can find. I snack on that stuff all day long. Also, you want some healthy fats. They aid considerably with tons of b12 and have a very high dense property so it speeds up your metabolic rate. Try to switch up chicken with flank steak, pork loin, turkey breast, ect. Finally, kidney beans and just about all other beans are a good side dish your going to want to add in.
