After reading all of the posts, to summarize....
Nail a good repeatable breakfast, like oats + protein powder + some low fat cheese or meat you can eat day in and day out without trouble.
Make two big sandwiches and eat those as your main solid food meals.
Have an MRP with Skim Milk 3x a day.
Track your calories is easy this way, either have 400, 500, or 600 calories and make sure you have 50 grams protein per meal.
Do this consistently, and you'll gain muscle, and you can figure out how much to eat, to gain muscle with minimal fat.
If you need to cut fat, and that's the bottom line, do this first. The same meal approach will still work.
Eventually, after just learning to prepare your meals, as simple as these are (they should take you like 15 total minutes per day), you'll realize you can go the extra 15-20 minutes and start preparing better meal choices.
Take a greens supplement to counter you arent eating alot of veggies, with the above meal plan and you'll do well.
This of course - sucks compared to what you could do instead, but it will work, and has worked for many people trying to add muscle in college, and in less than ideal eating circumstances.
