Changing my bad diet for some results?

Hey there, I'm a pretty athletic guy 21 years old 6'3'' weight lifter and runner. Ive been thinking about what changes I want to make for the new year, and i think my best idea would be my diet. I feel like that is whats holding me back from having a phenomenal physique! I'm not all that fat to begin with but I've never quite had a 6 or 8 pack abs but close on the 6 im rocking a solid 4 pack right now haha. Anyways I usually sit down on the bike after lifting for an hour and go pretty hard usually do about 1000 calories and call it a day. My diet isnt all that good though, ive cut french fries out of diet, I just want maybe like a meal plan or something for 7 days a week, stuff that tastes great and is good for you! Ill eat just about anything so no worries there. Thank you if you help me out!
