I would strongly recommend slow cookers. You can leave it in the morning and get it in the evening. The recipes are straightforward and require little actual cooking knowledge.

Even better you can easily cook large quantities so you're not even cooking every day.

My healthy favorite is slow-cooked stew combined with rice-cooker brown rice/quinoa - both are set on timers so they finish just before we get home - so no reheating.

I second this advice. A slow cooker is really ideal for your use case and can have some dramatically amazing results.

Still, you can't slow cook something like a pan-sautéed chicken breast. But many people, particularly single people, simply don't want to expend the effort for the reward. I have no problem with that; been there, done that.

I make a slow-cooker vegetable soup: low-sodium V8 juice with whatever chopped vegetables and beans I feel like / have on hand, typically kidney beans, carrot, onion, mushroom, bok choy, garlic ...

It takes me about a half-hour to chop up the vegetables, but one round makes a lot of soup.

Yeah, you can basically throw some pork, spices, and a beer in a slow cooker and come home to awesome pulled pork that you can eat all week.

I used to do the same thing. I think the best way to get out of that cycle is to start trying to cook something good just 1 day per week. The rest of the week can be trash, but just plan 1 good recipe.

In the beginning, making a new dish takes forever and feels really stressful because it's all unfamiliar, but if you do it enough, it becomes something you can do on autopilot with very little thought or planning. Even having just 2 or 3 autopilot recipes that you've perfected logged in your brain somewhere makes such a huge difference. That doesn't mean you have to cook them every night, but you can at least break up the monotony and unhealthiness of your current meal options.

Plus, at least for me, having a meal that is healthy and actually tastes really good makes me so much more productive when I get back to work.

That's a really poor excuse. Healthy meals can be just as hands off as TV dinners and french fries.

1. chicken breast 2. broccoli 3. noodles 4. some sort of oil 5. salt

Put all of the above in a pan, stir it around, cook (covered or uncovered, play with it) for about 7-13 minutes.

Try different mixtures. Try different lengths of time. You don't even have to watch it unless you're concerned that your range might explode or something.
