Meal prep a month of meals

Hello all, <br>I'm wondering if anyone can help me with a meal prep, I'm a first year university student, and will be leaving home soon, I've been told that I will have access to a refrigerator, but not a stove, I can use a microwave, I've been trying to find ways to have a balanced meal, without having to constantly rely on takeout, I was thinking maybe meal prep one day a week, I'm not really sure how much I should cook in one go to last me the rest of the week, I don't want to overcook, and have too much food in my fridge, I also don't want to not cook enough and have to rely on takeout. <br>I've been trying to make a meal plan, but I don't know how much I should cook.<br>Has anyone done this before? <br>Or meal prepped?<br>I would really appreciate any advice you can give.<br>Thanks so much in advance.
