Good lord you are OVER thinking this. Try and get varied sources and balance it in the long term the DAY and you'll be fine. get plenty of protein, veggies, fruits etc and your golden.
Good basic way to think of it. Get Protein and Something else with every meal. It can be as simple as some meat and an apple. A Big salad with meat, maybe a hard boiled egg.
Hell even just grabbing a nice half a chicken LOL Thats balanced. A nice whack of protein and fats. If you have time add some veggies but hell dont sweat it planty of time in the rest of the day to eat them.
Once again aim to get a LOT of good food over the long run and your fine.
Hope that helps,
