Every time I am at a congee shop, I wonder if the congee business might be the most lucrative and relaxing in the restaurant industry. Your main ingredients are rice and water (and stock, but that's also mostly water), which are dirt cheap. You make one big vat of porridge beforehand. Your menu can be vast, but each of those variations (pork, egg, seafood, whatever) requires just a tiny bit of cooking or heating up at the end. And congee is such amazing and versatile comfort food that people will flock to it for breakfast, lunch, or hangover relief.
My latest congee "effort" makes use of stir-fried chicken and goji berries. The latter is because I had leftover meat from my Orange Sesame Chicken, and the former because I just bought an expensive bag of organic gojis that I should cook with instead of snacking on like raisins. I don't know how many of the antioxidant claims attributed to gojis are true, but I'll keep eating them if they are reputed to help your eyesight. (Food blogging and other frequent computer usage doesn't exactly do wonders for myopia.)
