What should I bring for 4 days worth of food?

Going on a 4 day trip, 3 nights. I have never gone on anything longer then 1 night and was wondering what are some good things to bring for food. I was thinking of pancakes and oatmeal for breakfast, maybe some pasta for dinner? I was also planning on bringing protein bars and trail mix. Any suggestions on what I could bring for breakfast, lunch, supper and snacks?

EDIT: Forgot to add that I will be backpacking
