Are you going for radical change or small steps that can stay permanent?
Listening to all the good advice is good, but I would focus on finding ways to eat your chicken without frying it and covering it with cheese (no chicken parmigiana) and find some veggies you like and how you like to cook them (or eat them raw without a pile of ranch with each bite). Then again, eating those things is probably better than tv dinners and hot pockets, so if that's your first step then
If you're getting rid of eating out cold turkey and you can do it, great. But if you feel like you could fall off that wagon at any time, just make a rule that you can only eat out once a week or only get fast food once a month or whatever is easy to accomplish. Once that habit sticks you'll end up going even less often.
