Not sure if 15-20 minutes is too long for you but that's how long most dinners take for DBF and/or I to cook for two. Rice takes 10-15 minutes and so does cooking chicken and vegetables. Then you can decide if you want to make rice/chicken/vegetables for a Mexican, Chinese, or Thai meal! For Mexican, we add a can of Cuban style black beans and guacamole. For Chinese we add some sort of sauce (General Tso's probably) and peanuts. For Thai we just add curry paste with coconut milk or a curry sauce from a jar. Once we got into the swing of regularly cooking dinner it became astounding how quickly we could turn around a really satisfying dinner.
Life goes by pretty fast. If you don't stop and look around once in a while, and do whatever you want all the time, you could miss it.
