How is my diet? How should i improve?

Im in highschool and right now i run about 2 miles a week. So heres basically my day foods: For breakfast i will usually just grab a bagel (no spread) on my way out of the door or sometimes a lean pocket breakfast/ waffels. Then around 2nd period i am starving and usually eat like 6 oreos or teddy grams or sometimes, but not most, slices of apples. then for lunch i have yogurt, ham on weat bread (no toppings, sometimes american white cheese) and a gronola bar and maybe some cookies or crackers if we have some. Im asking if this is a good athlete diet because it seems like i am always hungry and looking for food and all that i have to my convienence is processed snacks. thanks.
