Moving out -- yet still eating well. What do you recommend?

[AlfilRey]

I´m 19 and I´m moving out within the next 2-3 days. Until now I have had a pretty good, well balanced diet. My mum puts a lot of effort into buying quality food and cooks some very complex meals. (Don´t get me wrong I cook 80% or so of my/our meals, but she does all the shopping and cooks the more complicated meals).

Now that I will be living on my own, I don´t want my health to suffer. In fact, I want it to improve.

I currently weigh 150 pounds and am just under 6, 1". My goal within the next 12-20 months is to reach about 175-180 pounds. I go to the gym and do mostly swimming / running but about 25% of my time is spent doing weights. I might shift that % around in the near future and focus more on weights.

My question is:

What food should I buy as a student who wants to eat really well but doesn´t want to dedicate 2 or 3 hours every day to shopping/cooking?

I figure there are two main categories:

1. Food that you cook, but that isn´t overly time consuming. e.g. chicken fillets, steak, pasta, etc.

2. Food that doesn´t need to be cooked, but that is very nutritious. e.g. fruit, peanut butter, milk, etc.

I´m sure that a lot of people on this forum know a heck of a lot more about this than I do. If anyone could give me a few tips, it´d really be appreciated.
