I agree with Moonjumper, don't ask your mom if you can do it take the inecitive and show your mother that you can and will cook for yourself. I know it may sound mean but you have to lay down the law, it's your body and if you don't want overly processed frozen veggie dinners in it you shouldn't have to eat it.
You may have a few dissagrements with your mother, and that can be hard if you two are close, but when you look back on it in a few years you'll both be happy that you stood up to the plate and did what needed to be done.
