When someone is sick, grieving, had a new baby, etc, I like to bring something fresh and healthy, like grilled chicken tenders with roasted vegetables, wild rice, fresh fruit or artisan bread. If they have young children or picky eaters, a "build your own" taco bar with taco chicken, ground beef, or sweet pulled pork with good tortillas and all the sides (salsa, pico, guac, rice, refried beans).
