This is a bit different from your desire maybe, but I use MyFitnessPal and try and hit a high protein and fibre goal. I'm not perfect at this by any means but to an extent it 'gamifies' healthy eating and makes achieving it rewarding.
So for instance I will make a healthy treat with 120g lentils, 30g oats, 15 or 30g cocoa powder, skimmed milk and sweeteners.
I'll try and get 30g of fibre as recommended by the NHS, and 1.2g per kg of protein because I do strength training (If you don't then you only really need 0.8g per kg- but protein can be filling.) It's fun to try and hit the targets in the app.
I don't really cook- warming half a tin of lentils and stuff takes 5 mins.
Making scrambled eggs in the morning doesn't take long and I'l have a piece of fruit beforehand while I CBA to cook.
I try and take all my spare money out so I don't buy just eat etc lol.
I know this is a different slant on it though. Arguably shite food, but you get more excited about it.
