Yeah, me.

Here's the rule of thumb: do you think the food benefits from being cooked unevenly? For meatballs as you mentioned, I'd sear them in a frying pan to get a little bit of crispiness before I cook them through in the sauce in the microwave. Hunters chicken, cakes, seafood, all good. The microwave will cook far more evenly than a convection oven, though sometimes the unevenness is desirable.

You can steam potato from raw in the microwave, just need to put some water in a bowl next to the potatoes plate. Or use a special bowl made for this. It's quicker than using a steamer, and just as good.

Super quick scrambled eggs.

Steamed broccoli.

Baked potatoes.

Chicken (small strips and 50% power)

Cake in a mug?

From time to time, just some veggies to go along with air fried chicken.

But that's because I don't own a stove, all of my cooking is handled by an air fryer, rice cooker, and the microwave
