Did it come with a steamer basket? Because if so, put some seasoned veggies up there and they'll cool and drip flavor down into the rice. It is tasty and convenient.
Rice cooker is nice cooker.
If it didn't come with a steamer basket, it's worth getting one. Rice and steamed whatever is a very easy meal.
You're supposed to be able to stick an egg in with the rice too, but I have yet to be brave enough to try it.
I live off a rice cooker. I mostly use them to cook quinoa, but various rices and even lentils too. That said... possible paranoia inbound. Does the bowl that holds/cooks the rice have teflon? I am literally convinced that I was poisoned by mine with PFAS. Really, look into it. Teflon is BAD. That shit is in everyone to some degree, but I got some really fucked up neuortoxicity symptoms after using mine. No joke, just do some research on that shit, I know I sound like a loon. If yours isn't stainless steel or some other non-teflon (non-PFAS) design, consider getting one of those instead. I deeply regret that I didn't.
