Best device for cooking meats fast and easy

Hello! My household is starting a journey to avoid highly processed foods, but with a lot of limitations. We're trying to select a device that will allow us to cook a lot of meat (chicken, turkey and pork) indoors quickly and without much interaction from us.

We're all disabled and very busy on top of it, so we can't stand in the kitchen cooking or leave a device on for much longer than an hour. We don't have any outdoor space, and our kitchen is just a small apartment kitchen, although we do have about 16” x 20” of space available on our countertop.

We're also hoping that the meats will actually taste good and be moist. The oven seems to take a long time and leaves the meats dry.

Does anyone have any recommendations for countertop devices that could help with this?

Thank you!
