I find a Thai curry is super fast and really easy.
This post on reddit even takes another shortcut by using a bag of already cut up frozen veggies:
Thai curry cheap(er) and healthy(er) than take out. This recipe is just four "ingredients" - raw skinless boneless chicken, curry paste, coconut milk, frozen veggies. See the poster's instructions and images and loads of good comments under the post on how to make the flavors even better and what curry pastes folks prefer.
While I wouldn't normally use frozen veggies, I totally get how they would be a huge help if someone couldn't stand or chop for very long.
Plus, while the method described in the link above says to fry/brown the cubed chicken before adding to the curry, I've taken a shortcut and just thrown the raw meat into the curried coconut milk. While that does make for a different texture and flavor, it's just that: different, and not bad at all. Also, you don't even have to fry the curry paste before adding the coconut milk. So there are lots of shortcuts to make less standing time and speed up the preparation.
The only slightly tricky part is to time all your additions by how long they will cook and how done you want them. Very hard or dense veggies like raw potato or raw squash or eggplant should be mostly cooked first - either boiled in water 20 minutes (strain afterwards - do not add the water to the curry unless you like it watered down! reserve cooking water for broth or other soup if you wish) or microwaved to partway/mostly cooked if you microwave. Then, everything else just takes about a 20-35 minute simmer in the curry paste and coconut milk - depending on the size of your "cubes," and the cooking temperature, and your preferences.
The variations possible are SO fun. I really like seeing the colors of skin-on cubes of purple eggplant and bright orange squash or sweet potato in a yellow or green curry. And of course, other proteins can be substituted for the chicken depending on taste, diet choices, budget or time. Dumping in frozen shrimp (peeled) could be even easier than cubing raw chicken, or a drained and rinsed can (or two cups cooked) of chick peas tastes great and is super easy, too.
Fun additions if they are not too taxing for you are (added at the end just before serving) fish sauce, fresh basil leaves, and/or chopped cilantro on top of each bowl.
Serve over rice and you have a hearty, filling meal.
