Always have brown rice on hand as well as a variety of spices/garlic/etc. Cook a ton of brown rice once a week and keep it in a tupperware in the fridge. Then you can just fry it up with some egg/veggies/spices or whatever and have fried rice whenever you need food asap. You could probably stretch what $$$$ you paid for that Thai food into 3-4 meals.
I also keep Kimchi (pickled Korean cabbage, sooo good) in the fridge. That, or fruit, is my "fast food" lol :D
