"food that's cheap, requires little to no cooking and isn't bland."
I dare say this is one of those three aspects, pick two situations.
Processed stuff tends to be more expensive for the calories it provides -- you mentioned frozen pizza but try that here and you will struggle. If something is tasty then they creep prices up a tiny fraction at a time (or reduce the size of it and keep the price the same) and eventually you end up expensive while the blander stuff stays low. You can try using spices and oils on the blander things but that might take a bit of work.
Your best bet if you really don't like cooking (I recall the stir fry conversation the other month) would be buy in bulk, make a bit pot (or three), freeze it and then you only need to warm it through when you want something. Rice with bits in, tuna pasta, stews, chilli, shepherd's pie, curries, porridge is seen as something of a sweet breakfast by many but it has many uses. Get a bit more adventurous and you can try making a base that you adapt over the week -- the same meal every day for a week gets monotonous but if you have a pot of mince you can have pasta with it one day, rice another, mix in some curry sauce for another, potatoes another day, maybe some pie another, cheese sauce for another and now it is the weekend again, or spin it the other way and rather than basing something on meat base it on pasta or something and then put different things in it/with it every day.
If you can find something you enjoy in the less desirable cuts of meat that works too -- I love lamb liver, heart and kidney, cow brain, cow tongue, rabbit and so forth, however I have had bad liver before and where I can at least chew a rubber steak this was a hold your nose and force it down job.
