Dude, eating out is more expensive then buying and cooking your own food. Eggs are fast to cook, can just hard boil a bunch of eggs keep them in the fridge, oatmeal 2 min in microwave and done, tuna and rice cakes are easy go to meal, buy a George Foreman grill, cook some meat on there you can buy a huge pack of frozen burgers, this was my exact diet in college (along with a ton of beer). Its very inexpensive and fast prep meals.
