If you handed me a plate with french toast, sausage, and fruit I'd be thrilled. It would be the sort of thing I'd order when having breakfast on vacation and because you gave me turkey sausage and fruit I wouldn't feel guilty about the french toast at all.
But if you really want another item, I think eggs would be the most common item. Or you could do sliced tomatoes that you top with cheese (my mom used to do equal parts parmesean, ricotta, mozzarella and mayo and basil but it is a little rich) and then broil.
