Can someone critique my diet?

Pasta

Chicken breast (seasoned with salt, pepper, knorr cubes, paprika)

White bread

Turkey deli

Peanut butter

Protein powder

Fruits (oranges, banana, kiwi, blueberries depending on how much calories I need)

Spinach

Walnuts for my evening snack if there is room

This is pretty much my main diet and I adjust the portions accordingly.
