Rice and beans are tasty! Anything other than salt and maybe some pepper is fucking gourmet.
I'm not trying to say that you're wrong. I'm just saying that there's already enough horrible shit to worry about without underestimating the simple pleasure of rice and beans.
Side note: onions and garlic will grow just about anywhere. Throw some of that shit somewhere in your rice and beans and you've got a fucking party in your mouth.
What type of onions? I've only grown green onions, which you can grow indoors in a plastic cup with water and a paper towel at the bottom as long as it's near a window with unobstructed sunlight.
