I like grilled chicken breasts and the turkey burgers are a good idea too. Or you could get some chicken sausages or brats if they do those. I buy a brand called Al Fresco that are really good. For salad would they go for a simple tomatoes cucumbers and onion??
I find family to be the most difficult when I am watching what I eat. My DH is not a problem but his Mom still puts a whole stick of Blue Bonnet in the mashed potatoes!
