Cauliflower rice: I thought it was just a gimmicky bullshit fad but goddamn is it ever so tasty and also fun to make. Remove the stems from the florets and use the largest grater attachment on your food processor, it takes approximately 1 min to make enough for 2 people. Lightly stir-fry or steam with onions and mushrooms for added flavor.
Eggs: steamer basket in a small saucepan with a small amount of boiling water, 7 minutes and then cooled as fast as possible (we just run cold water over it for a while). Perfectly set whites that aren't rubbery, perfect yolks that are just a tiny bit runny in the center, super easy to peel (tap each end hard and then the shell practically slides off on its own).
Fish: also surprisingly easy and tasty to steam. Salt, like, a LOT, let rest for up to 3 mins depending on your preferred consistency, wash off thoroughly, place in a steamer basket on top of mushrooms, onions or vegetables of your choice, maybe add a little soy sauce and then steam (lid on) for a few minutes (like 4 mins maximum). Serve with aforementioned cauliflower rice or green beans sautéed in canola and/or sesame-seed oil over high heat until they begin to brown a little bit (I don't even like green beans but they taste delicious cooked this way, even if they're frozen). If the fish is already prepped this takes 5-10 mins of active work, if not it takes a few minutes more in addition to the time it takes to cure the fish.
If you have a whole boneless side of fish eg. salmon, and you don't wanna bother with cutting it into portions, cure it, rinse thoroughly, place it skin-side up on a lightly oiled oven-proof tray (maybe with a few sprigs of rosemary underneath if you have it) and then chuck it into the oven. Turn on broiler and set it to max, keep an eye on the fish and when the skin begins to char a little (10 mins in our old oven), remove it from the oven. The skin comes right off, the fish is still juicy and you can serve it with the green beans you just sauteed while the fish cooked.
Our weeknight meals have become both much less complicated and time-consuming as well as much more satisfying. Two people can make varied, flavorful and healthy meals with less than 15 mins of active work and not too much mess.
tl;dr: cauliflower rice = good, steaming = good, curing/dry-brining fish = good.
