Totally. Sit and eat with your kids. Make food with them, clean up with them. Make them seriously good times. Teach them good food habits, good life skills (chill out from the rat race and sit down for a decent meal), and improve both their and your own social skills. I doubt that particular meal substitute stuff is truly complete, and I do believe that variety is a good thing. Eating good food is good for the soul, as it can be one of the different types of beauty we can have on our lives.
