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.
