Hey Annett!
I'm the only LC'er in my family, too. What has helped make mealtimes so much easier is having a small George Foreman grill that I can cook a piece of meat on, just for me. While I cook a pasta dish or casserole for my family I just throw on my main course on the grill and steam my veggies in the microwave. It's super quick, and many's the time that they want my dinner instead of theirs!
Good luck!

Karen
