Do you have an oven in some common lounge? It seems daunting to cook at first, but it's really pretty simple.
Example. You have no idea what you're doing.. Go to store. Buy barbecue sauce, some pieces of chicken of any kind, foil pan. At it's most basic, open that chicken, rinse it, throw it in the pan.
Put the pan in the oven at like 350 or really who cares.. 300 to 400. It's not exact. Add the barbecue sauce somewhere along the way, just pour it on if you must.
Hardest part is figuring out when it's done. You can go by feel and look but when you're new that's tough. I use a thermometer plenty, it really helps you nail down what temps correlate to what amount of done-ness. You can look up cook to temps online. If not look up how to tell it's done and follow those. Don't eat it undercooked, obviously, but if it's overdone well fuck it just cook it less next time around.
Anyone who tells you a specific oven temp & cook time is full of it because it will change dramatically based on your equipment and your meat.
My roommates and I cooked plenty in college. Sometimes extravagant meals but more often a basic meal just to give us a dinner that night while we were busy studying or whatever. One of the easiest ways is to throw some kind of meat and thick cut veggies into the oven for an hour. It requires little work to check up on and in the end you have a decent meal + leftovers for lunch the next day.
