I started p90x and would like someone to check my meal plan?

So I started p90x a week ago and I started the nutrition part 4 days ago. I don't know if I am eating too much or the correct things.

I will start with letting you know I am in camp and can only eat camp food.

I am 26 years old and am 225lbs and 6 foot 2 inches tall. I am a little on the chubby side but not obese or anything, I work in construction and work very hard for 10 hours a day and this is my meals while working everyday(I eat less when I go home)

Morning (5:00am)

3 egg whites

bowl of fruit with 1 tablespoon of yogurt

side of beans with sauce (like 4 tablespoons)

oatmeal or red river or cream of wheat (whichever they serve that day) with cinnamon and a little fruit for flavor(blueberries or strawberries or raspberries)

2 small cups of Soy So Good Vanilla flavour(tiny little kid sized glasses) 1 of the glasses i pour half into my oatmeal

1 cup of water

First break of day at work (9:00am)

Vanilla yogurt

Small bowl of watermelon

1 tuna sandwich on 60% whole wheat

2 cups of water

Lunch(11:30am)

3 small chicken breasts(2 would equal 1 normal size so technically 1 and a half regular chicken breasts)

2 cups of water

Second break(2:30pm)

Vanilla yogurt

1 small chicken breast

1 small bowl of broccoli with low calorie ranch(3/4 packet)

2 cups of water

I do my workout at 6:00pm

I drink about a liter of water during my workouts

I eat dinner at(7:30pm)

Different everyday but usually 1 or 2 meats and whatever mixed veggies or salad with no dressing

2 cups of Soy So Good Vanilla Flavour(same kid size glasses)

1 cup of water

Is this eating too much or too little or is any part of it not good for p90x?
