Not-too-heavy meal to prepare ahead?

My family is coming to visit at the end of May and I’m not quite sure what to serve when they arrive. My mom is pretty sensitive to heavy meals after travel, so the classic make-ahead meals like chili and stew are probably out. If it was just my mom I’d probably make a salad, but my aunt and uncle have a more substantial appetite. I’d love to make something I can prepare ahead and either just reheat or finish while they’re unpacking. I’m vegetarian but they are not and I’m willing to make a meat dish and eat sides or something else.

I’d appreciate any suggestions!
