Generally, you want to aim to have a solid breakfast, pre-workout, post-workout, and pre-bed meal. I suggest gettign most of your carbs at breakfast, pre workout, and post-workout. Your 155 pounds so you need 155-200g protein per day. Don't neglect fats.
This is my daily diet just for kicks:
Meal 1: Oats, eggs, fruit, skim milk
Meal 2: Meal replacement bar (homemade with oats, natty PB, whey, and milk)
Meal 3: Turkey Sandwich, 1 yogurt
Meal 4: Whey, 1 banana
Meal 5: Chicken, sweet potato, brocolli
Meal 6: Cottaeg Cheese, Nattty PB
I left out the quantities because it varies from person to person. Someone who is 5'6 (me) needs a different amount of calories than someone who is 5'10.
