I think you should set yourself 3 meals a day. Something like eggs on wholemeal toast would make a good breakfast and some cracked black pepper to reduce the blandness.
Try learning to cook spicy foods, there are loads of healthy curry/chilli recipes on the net to try. The spicyness may tantalise your taste buds a bit more.
No matter how bland/unsatisfying you find it, i think you should stick to 3 meals a day just get yourself into a normal eating pattern. Obviously cut out the ready meals etc too and learn to cook as a new hobby!
If this is rubbish advice sorry, reading this thread has boggled my brain lol.
