on the too lazy to cook front-we had allot of this when both of us were commuting long distances daily for work and the kiddos were little. the only thing that helped break the habit was to look at what food we always defaulted to and setting up our freezer/pantry so that it was as fast if not faster (and MUCH cheaper) to easily do it on our own. here are some things that worked for us (YMMV)-
pizza-we had frozen pizzas with the basics we knew we wouldn't always have on hand (for ds-cheese/pepperoni/olive, for the rest of us cheese and maybe sausage). we would top these with stuff that could be on the shelf or in the freezer at the ready-water packed artichoke hearts (like $2.49 a can and we would use the rest up in salads over the next couple of days), shredded bbq chicken (if i made chicken i shredded some and mixed it w/bbq sauce and froze in small containers), we always had onions on hand as well as other veg-easy enough to chop while the oven pre-heats.
Mexican-i would premake ground beef with seasoning, shredded beef with enchilada sauce (actualy did this yesterday). it went into small containers that could quickly microwave defrost. with tortillas at the ready (freezer) or taco shells on the shelf it was microwave defrost/heat and then either make the tacos or roll the enchiladas (top w/second premade container of sauce and whatever shredded cheese was in the freezer) and we were good to go.
food in general-ground beef can be browned, drained and frozen easily. put it in measured bags to pull out to make a quick batch of sloppy joes, season and add to pasta sauce. chicken and beef (pork as well) shred easily and can be frozen after cooking. pull out and add to sauces for bbq sandwiches, pasta alfredo w/chicken....
i'm a big fan of scratch made stuff but i've only been able to do more of it since i no longer have long work commutes/hours and more time to myself-it's just a simple reality of life so there's no sin in using premade store bought or homemade b/c both will save a ton over pickup or delivery food.
