You can definitely cut most things down to meet your size, but you might start by looking in a place that specializes in simpler stuff. I always recommend Start Cooking to college students: http://startcooking.com/

Otherwise, simple single-serving recipes that were regulars for me: all sorts of pasta, grilled cheese, stir-fry, tacos, salads...

And as far as "single-serving" goes, you'll prolly find that larger things are actually better to cook in college -- cook a ton of chili at once and save it for dinner for several days.

I like to prepare meals in bulk which also allows me to spend a good amount of time on one dish instead of rushing it. About once a month I make enough pasta for a wrestling team and package it up with meat sauce, works well for reheating in a microwave somewhere on campus.

Also when I was a freshmen I stocked up on 4 large boxes of ramen, since then I have found many ways to use those in meals which is a good place to start for someone who does not know how to cook. It's hard to mess up ramen noodles and it's easy to make them far better with a little work. Start with adding in real chicken and then let your mind go crazy with other ideas.

If you're not sick of Ramen yet, check out this site - http://www.rasmussen.edu/articles/ramen-noodle-recipes.asp

These recipes have saved me an exorbitant amount of money by convincing me not to go to Whataburger and to eat Ramen instead. The 50+ recipes on the site all use Ramen noodles as their fundamental base, and then work from there. Some good. Some bad. But, there is without a doubt at least one thing that would appeal to you. Give it a shot.

As I get busier and busier with school, the chance of me realistically cooking a nice wholesome dinner for myself is very, very low. I started to experiment with freezing pre-cooked meals, and I've loved it so far. I find time one Saturday and cook ridiculous amounts of food. I then individually package and freeze it, and then just heat it up when I'm hungry. Grocery bills are very low, while convenience and taste are very high.

This site offers many tips and tricks on how to get started "feeding the freezer":

I agree with the others who said to go ahead and make the full recipe and freeze/refrigerate the leftovers. If you know you'll have extras when making it, you can do things to make the freezing process easier. For example, if you're making lasagna you can slice it into individual portions and wrap them individually. That way, when you decide you want to have it for a quick lunch you can just grab a single square without having to defrost the whole thing. If you want to avoid waste, making a meal plan is a must. Get a list of meals you want to try out and see what the ingredients are. Try to plan them out so that ones with similar ingredients are made within a day or two of each other, that way when you aren't stuck an entire package of an ingredient when the recipe only called for a small amount.

You know I ran across something that Stouffer's makes called a Chicken Alfredo Flatbread Melt. They are excellent, and only cost a couple bucks. Would be great for late night snack or even a meal. Very filling! They also come in a few other varieties. Check em out!

Last, if you still can eat Ramen, check out this website called Ramenlicious. They have awesome single serving recipes.

I've recently become addicted to Trader Joe's. If you have a TJ's nearby, go there. The food is better quality and cheaper. They have a whole section dedicated to pre-cooked meals. Slip it in the microwave, and you are golden!

If you can't find any single serve recipes, you could always cut down the ingredients so it will only yield one serving. Alternatively, you could make the whole recipe and save the leftovers for later in the week. A good example of this is Classic Red Beans and rice. Very easy to make btw & healthy.

Every Sunday morning, College Candy has a column called Intro to Cooking. The recipes are all pretty simple, can vary from breakfast items to dinner to dessert, and cover many of the basics.
